The split()<\/code> is a built-in method in Python and is used to<\/strong> split a string into substrings (words) based on a separator or delimiter<\/strong> which it takes as an argument. It returns a list containing the substrings separated by a specified delimiter(separator).<\/p>\n\n\n\n

\"Splitting\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

In simple terms, you have a sentence and you want to split it into words making them different entities, you can use the split()<\/code> method and it will return a list containing the words.<\/p>\n\n\n\n

sentence = \"You are good\"\n\n# Splitting sentence into array of words\nresult = sentence.split()\nprint(result)<\/pre><\/div>\n\n\n\n
The above code will split the string stored in the sentence<\/code> variable into three words within a list.<\/p>\n\n\n\n
['You', 'are', 'good']<\/pre><\/div>\n\n\n\n
You may be wondering how the string got separated when there is no delimiter specified as an argument.<\/p>\n\n\n\n
Syntax<\/h2>\n\n\n\n
.split(sep=None, maxsplit=-1)<\/strong><\/code><\/p>\n\n\n\n
sep<\/code> – If sep<\/code> is not specified, the whitespace character is used as the delimiter otherwise, the string will be split based on the specified sep<\/code>.<\/p>\n\n\n\n
maxsplit<\/code> – If maxsplit<\/code> is not specified, the string will split until it reaches the end, creating as many elements as possible. Otherwise, if maxsplit<\/code> is specified, the string will be split into maxsplit + 1<\/code> elements. For example, if you’ve specified maxsplit=1<\/code>, then the string will split into 2 elements.<\/p>\n\n\n\n
Splitting based on delimiter<\/h2>\n\n\n\n
Suppose you have a comma-separated sentence and you want to split that sentence into a list of substrings based on the comma, you can simply pass the separator as a comma (\",\"<\/code>) and be done.<\/p>\n\n\n\n
sentence = \"Sachin, Yashwant, Rishu, Abhishek, are good\"\n\n# Splitting sentence based on comma\nresult = sentence.split(sep=\",\")\nprint(result)<\/pre><\/div>\n\n\n\n
If you run this code, you’ll get the following output.<\/p>\n\n\n\n
['Sachin', ' Yashwant', ' Rishu', ' Abhishek', ' are good']<\/pre><\/div>\n\n\n\n
You can see that the split(sep=\",\")<\/code> split the sentence where the comma is placed and you get five substrings within a list.<\/p>\n\n\n\n
You can split the string based on any delimiter such as commas, spaces, tabs, semicolons, etc., depending on the specific requirements of the data being processed.<\/p>\n\n\n\n
Suppose you have the data containing names separated by a weird expression and you want to take out the names from the data.<\/p>\n\n\n\n
sentence = \"Sachin\/<>\/Yashwant\/<>\/Rishu\/<>\/Abhishek\/<>\/Yogesh\"\n\n# Splitting\nresult = sentence.split(sep=\"\/<>\/\")\nprint(result)<\/pre><\/div>\n\n\n\n
This will work as fine as the code from the previous and you’ll get the list of names from the data and you can perform whatever operation you want.<\/p>\n\n\n\n
['Sachin', 'Yashwant', 'Rishu', 'Abhishek', 'Yogesh']<\/pre><\/div>\n\n\n\n
Using maxsplit<\/h2>\n\n\n\n
If you have a specific number in mind for how your string should be split, you can use the maxsplit<\/code> to specify that number.<\/p>\n\n\n\n
sentence = \"Sachin\/<>\/Yashwant\/<>\/Rishu\/<>\/Abhishek\/<>\/Yogesh\"\n\n# Using maxsplit\nresult = sentence.split(sep=\"\/<>\/\", maxsplit=3)\nprint(result)<\/pre><\/div>\n\n\n\n
In the above code, the maxsplit<\/code> is set to 3<\/code> which means the string will be split into four substrings.<\/p>\n\n\n\n
['Sachin', 'Yashwant', 'Rishu', 'Abhishek\/<>\/Yogesh']<\/pre><\/div>\n\n\n\n
The string got split into four substrings instead of three despite setting the maxsplit<\/code> to 3. This happened because, by default, one is added to the number of maxsplit<\/code>, which means maxsplit=3<\/code> is equivalent to maxsplit=3 + 1<\/code>, resulting in a maximum of 4 parts after splitting.<\/p>\n\n\n\n
Example<\/h2>\n\n\n\n
Assume you have a file containing a person’s information (name, age, and email address), and you want to access the data from the file and perform some operations on it.<\/p>\n\n\n\n
def get_details(filename):\n    with open(filename, \"r\") as file:\n        lines = file.readlines()\n        result = [line.split() for line in lines]\n        return result\n\ndetails = get_details(\"names\")<\/pre><\/div>\n\n\n\n
The function, get_details<\/code>, reads a file given by the filename<\/code> parameter. It then reads all the lines from the file using file.readlines()<\/code>. Each line is split into a list of strings using the split()<\/code> method, which splits the line based on whitespace by default. This creates a list of lists, where each inner list contains the individual words from each line.<\/p>\n\n\n\n
Finally, the function returns this list of lists, where each inner list represents the words from each line in the file.<\/p>\n\n\n\n
You can use the object (details<\/code>) to access information about a specific person.<\/p>\n\n\n\n
print(details[3])\nprint(details[1])\nprint(details[9])<\/pre><\/div>\n\n\n\n
This will print the information for the person on the third, first, and ninth indexes respectively.<\/p>\n\n\n\n
['Isabella,', 'isabellanguyen@gmail.com,', '30']\n['Sophia,', 'sophiamartinez@yahoo.com,', '28']\n['Charlotte,', 'charlotte.gonzales@hotmail.com,', '34']<\/pre><\/div>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
The split()<\/code> method is used to split a string into substrings within a list. You can also split your string based on a delimiter which you can pass as an argument to the split()<\/code> method and you can control the splits by setting a value to the maxsplit<\/code> parameter.<\/p>\n\n\n\n
