You can check if the string is empty or whitespace using an isspace() function and strip() function in python.<\/p>\n\n\n\n

You can also just use not string with if-else condition statement.<\/p>\n\n\n\n

Check if the string is “whitespace” in Python<\/strong><\/h3>\n\n\n\n

First, check if the string\u00a0contains<\/strong>\u00a0whitespace only or not by using a “isspace() function<\/a>” in python.<\/p>\n\n\n\n

A function returns true if any space and no charter in the string text else it will return false.<\/p>\n\n\n\n

\n# string only space\nstr1 = \" \"\nprint(str1.isspace())\n\n# string without space\nstr2 = \"\"\nprint(str2.isspace())\n<\/pre>\n\n\n\n
Output:<\/strong><\/p>\n\n\n\n
True
False<\/p>\n\n\n\n

Check if the string is “Empty”<\/strong> in Python <\/h3>\n\n\n\n
Empty strings are “falsy” which means they are considered false in a Boolean context, so you can just use not string.  <\/p>\n\n\n\n
Here\u2019s a function to check if a string is empty:<\/strong><\/p>\n\n\n\n
\ndef is_empty(string):\n\treturn not string.strip()\n<\/pre>\n\n\n\n
Example:<\/strong><\/p>\n\n\n\n
\nstr1 = \"\"\nif not str1:\n    print(\"Empty String!\")\n\n<\/pre>\n\n\n\n
Output: <\/strong>Empty String!<\/p>\n\n\n\n
<\/div>\n\n\n\n
If you consider whitespace also not in an empty string then use the strip() method, where the strip() method will remove all white space. So if there is only white space then the string becomes empty.<\/p>\n\n\n\n
\nstr1 = \"  \"\nif not str1.strip():\n    print(\"Empty String!\")\n\n<\/pre>\n\n\n\n
<\/div>\n\n\n\n
Q: How to get a number of spaces in a string in Python?<\/strong><\/h3>\n\n\n\n
Answer: <\/strong>Use the count() function to get the number<\/a> of spaces in the given string.<\/p>\n\n\n\n
str1 = \"Hello World \"\nprint(str1.count(' '))\n<\/pre>\n\n\n\n
