Introduction<\/h1>\n\n\n\n

First of all, What is the meaning of enumerating<\/strong>?<\/p>\n\n\n\n

The meaning of enumerating is to number or name a list of things separately<\/strong>.<\/p>\n\n\n\n

Python enumerate()<\/strong><\/code> function does the same thing as its name depicts itself.<\/p>\n\n\n\n

<\/a>Python enumerate()<\/h1>\n\n\n\n

Python enumerate()<\/strong><\/code> function takes a collection(e.g. a list<\/strong> or a tuple<\/strong>) and returns them as an enumerated object.<\/p>\n\n\n\n

The enumerate()<\/strong><\/code> function adds a number\/count to each item of the iterable object and returns an enumerate object.<\/p>\n\n\n\n

Here’s a simple example of<\/strong> enumerate()<\/strong><\/code> function usage:<\/strong><\/p>\n\n\n\n

greet = ('Welcome', 'to', 'GeekPython')\n\noutput = (enumerate(greet, start=0))\n\n# Converted enumerated object to list\nprint(list(output))<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
[(0, 'Welcome'), (1, 'to'), (2, 'GeekPython')]<\/pre><\/div>\n\n\n\n
<\/a>Syntax<\/h2>\n\n\n\n
\n
The syntax of<\/strong> enumerate()<\/strong><\/code> function is:<\/strong><\/p>\n\n\n\n
enumerate(iterable, start=0)<\/strong><\/code><\/p>\n\n\n\n
<\/a><\/h3>\n<\/blockquote>\n\n\n\n
Parameters<\/h3>\n\n\n\n
iterable<\/strong><\/code> – must be a sequence, an iterator, or objects that supports iteration.<\/p>\n\n\n\n
start<\/strong><\/code> – It is optional. If the start<\/strong><\/code> is not specified then the count will start from 0(default)<\/strong> else the count will start from a specified number and increment until the loop ends.<\/p>\n\n\n\n
greet = ('Welcome', 'to', 'GeekPython')\n\noutput = (enumerate(greet, start=10))\n\n# Converted enumerated object to list\nprint(list(output))<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
[(10, 'Welcome'), (11, 'to'), (12, 'GeekPython')]<\/pre><\/div>\n\n\n\n
We specified the start<\/strong><\/code> parameter which is equal to 10 and hence the enumerated output starts from the specified number.<\/p>\n\n\n\n
<\/a>Fact<\/h3>\n\n\n\n
If we see the above example, we converted our enumerate object into the list type and then print it.<\/p>\n\n\n\n
What if we don’t convert our enumerated object into a list type then what will happen?<\/p>\n\n\n\n
Well, the answer is pretty simple we don’t get any enumerated object<\/strong> instead, we’ll get the<\/strong> location of an<\/strong> enumerating object in the memory\/CPU<\/strong>.<\/p>\n\n\n\n
Example<\/strong><\/p>\n\n\n\n
greet = ('Welcome', 'to', 'GeekPython')\n\noutput = (enumerate(greet))\nprint(output)<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
<enumerate object at 0x0000016677A25E40><\/pre><\/div>\n\n\n\n
<\/a>Looping over enumerate() object<\/h1>\n\n\n\n
We can perform for<\/strong><\/code> loop to iterate over enumerate objects.<\/p>\n\n\n\n
my_obj = [\"Python\", \"Ruby\", \"JavaScript\", \"Java\"]\n\nprint(\"Looping over enumerate object:\")\nfor item in enumerate(my_obj):\n    print(item)\n\nprint(\"\\nLooping over enumerate object using start value:\")\nfor item in enumerate(my_obj, start=5):\n    print(item)<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Looping over enumerate object:\n(0, 'Python')\n(1, 'Ruby')\n(2, 'JavaScript')\n(3, 'Java')\n\nLooping over enumerate object using start value:\n(5, 'Python')\n(6, 'Ruby')\n(7, 'JavaScript')\n(8, 'Java')<\/pre><\/div>\n\n\n\n
<\/a>Performing enumerate() on<\/h1>\n\n\n\n
We are going to see the examples where we use the enumerate()<\/strong><\/code> function on different data types in Python.<\/p>\n\n\n\n
<\/a>String –<\/h3>\n\n\n\n
Python str<\/strong><\/code> type can be iterated so we can perform enumerate()<\/strong><\/code> function on it.<\/p>\n\n\n\n
Example: Performing enumerate() on string<\/strong><\/p>\n\n\n\n
text = \"GeekPython\"\n\n# Using loop to iterate and enumerating\nprint(\"Using loop to iterate and enumerating\")\nfor word in enumerate(text):\n    print(word)\n\nprint(\"----------------xxx--------------------\")\n\n# Using simple approach\nprint(\"Using simple approach\")\noutput = enumerate(text)\nprint(list(output))<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Using loop to iterate and enumerating\n(0, 'G')\n(1, 'e')\n(2, 'e')\n(3, 'k')\n(4, 'P')\n(5, 'y')\n(6, 't')\n(7, 'h')\n(8, 'o')\n(9, 'n')\n----------------xxx--------------------\nUsing simple approach\n[(0, 'G'), (1, 'e'), (2, 'e'), (3, 'k'), (4, 'P'), (5, 'y'), (6, 't'), (7, 'h'), (8, 'o'), (9, 'n')]<\/pre><\/div>\n\n\n\n
We can use start<\/strong><\/code> parameter also –<\/p>\n\n\n\n
text = \"GeekPython\"\n\nprint(\"Using loop to iterate and enumerating using specified number:\")\nfor word in enumerate(text, start=10):\n    print(word)<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Using loop to iterate and enumerating using specified number:\n(10, 'G')\n(11, 'e')\n(12, 'e')\n(13, 'k')\n(14, 'P')\n(15, 'y')\n(16, 't')\n(17, 'h')\n(18, 'o')\n(19, 'n')<\/pre><\/div>\n\n\n\n
<\/a>List –<\/h3>\n\n\n\n
We performed enumerate()<\/strong><\/code> function on list<\/strong><\/code> type in the example below where the first block of code gives<\/strong> the start value as 2<\/strong> and we used a simple approach in the second block of code<\/strong>.<\/p>\n\n\n\n
Example: Performing enumerate() on list<\/strong><\/p>\n\n\n\n
greet = ['Welcome', 'to', 'GeekPython']\n\nprint(\"Using enumerate on list using start:\")\nfor iterables in enumerate(greet, start=2):\n    print(iterables)\n\nprint(\"\\nUsing enumerate on list:\")\noutput = enumerate(greet)\nprint(list(output))<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Using enumerate on list using start:\n(2, 'Welcome')\n(3, 'to')\n(4, 'GeekPython')\n\nUsing enumerate on list:\n[(0, 'Welcome'), (1, 'to'), (2, 'GeekPython')]<\/pre><\/div>\n\n\n\n
<\/a>Tuple –<\/h3>\n\n\n\n
Example: Performing enumerate() on tuple<\/strong><\/p>\n\n\n\n
greet = ('Welcome', 'to', 'GeekPython')\n\nprint(\"Using enumerate on tuple:\")\nfor item in enumerate(greet):\n    print(item)<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Using enumerate on tuple:\n(0, 'Welcome')\n(1, 'to')\n(2, 'GeekPython')<\/pre><\/div>\n\n\n\n
<\/a>Dictionary –<\/h3>\n\n\n\n
dict()<\/strong><\/code> type contains key-value<\/strong> pairs, so we can enumerate()<\/strong><\/code> dictionary items (keys and values) separately.<\/p>\n\n\n\n
Example: Performing enumerate() on dictionary<\/strong><\/p>\n\n\n\n
values = {\"a\" : \"Geek\", \"b\" : \"Python\"}\n\nprint(\"Accessing values from dict and enumerating:\")\nfor value in enumerate(values.values()):\n    print(value)\n\nprint(\"\\nAccessing keys from dict and enumerating:\")\nfor key in enumerate(values.keys()):\n    print(key)<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Accessing values from dict and enumerating:\n(0, 'Geek')\n(1, 'Python')\n\nAccessing keys from dict and enumerating:\n(0, 'a')\n(1, 'b')<\/pre><\/div>\n\n\n\n
Example: Performing enumerate() on dictionary using start<\/strong><\/p>\n\n\n\n
values = {\"a\" : \"Geek\", \"b\" : \"Python\"}\n\nprint(\"Accessing values from dict and enumerating using start:\")\nfor value in enumerate(values.values(), start=5):\n    print(value)\n\nprint(\"\\nAccessing keys from dict and enumerating using start:\")\nfor key in enumerate(values.keys(), start=7):\n    print(key)<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Accessing values from dict and enumerating using start:\n(5, 'Geek')\n(6, 'Python')\n\nAccessing keys from dict and enumerating using start:\n(7, 'a')\n(8, 'b')<\/pre><\/div>\n\n\n\n
<\/a>Set –<\/h3>\n\n\n\n
set()<\/strong><\/code> type in Python is unordered, unchangeable, and unindexed<\/strong>, so when we enumerate them, the “set” item appears in random order<\/strong>.<\/p>\n\n\n\n
Example: Performing enumerate() on set<\/strong><\/p>\n\n\n\n
greet = {'Welcome', 'to', 'GeekPython'}\n\nprint(\"Using enumerate on set:\")\nfor item in enumerate(greet):\n    print(item)<\/pre><\/div>\n\n\n\n
Output<\/strong><\/p>\n\n\n\n
Using enumerate on set:\n(0, 'GeekPython')\n(1, 'to')\n(2, 'Welcome')<\/pre><\/div>\n\n\n\n
<\/a>Conclusion<\/h1>\n\n\n\n
As we discussed above, Python enumerate()<\/strong><\/code> function helps us to add counter to our iterable objects.<\/p>\n\n\n\n
You have seen the implementation of enumerate()<\/strong><\/code> function on the built-in data types in Python as well as you’ve seen how you can loop over iterable objects and enumerate them.<\/p>\n\n\n\n
You can use this function in many ways like enumerating the files in the particular directory to make the folder structure pretty<\/strong> or you can make a tool where a user can automatically number their files and folders easily<\/strong> or maybe something else.<\/p>\n\n\n\n
\n\n\n\n
That’s all for now.<\/strong><\/p>\n\n\n\n
