Python Keywords are set of reserved words that have specific meanings and purposes and can’t be used for anything but those specific purposes. These keywords can't be used as a variable name, function name or any other identifier. They are used to define the syntax and structure of the Python language.
In Python, keywords are case sensitive. There are 35 keywords in Python 3.8. All the keywords except
None are in lowercase.
Print was also a keyword in Python 2 but it is not a keyword in Python 3+ as it is a built-in function .
Ways to Identify Keywords:
We can get a list of available keywords by using
Here is a list of the Python keywords. Enter any keyword to get more help. False class from or None continue global pass True def if raise and del import return as elif in try assert else is while async except lambda with await finally nonlocal yield break for not
We can use
keyword module for working with Python keywords in a programmatic ways. The
keyword module in Python provides two helpful members for dealing with keywords
1. kwlist : It provides a list of all the Python keywords for the version of Python you’re running.
import keyword print(keyword.kwlist)
['False', 'None', 'True', 'and', 'as', 'assert', 'break', 'class', 'continue', 'def', 'del', 'elif', 'else', 'except', 'finally', 'for', 'from', 'global', 'if', 'import', 'in', 'is', 'lambda', 'nonlocal', 'not', 'or', 'pass', 'raise', 'return', 'try', 'while', 'with', 'yield']
2. iskeyword(): It provides a handy way to determine if a string is also a keyword.
import keyword keys = ["for", "while", "Shiksha", "break", "Devanshi"] for i in range(len(keys)): if keyword.iskeyword(keys[i]): print(keys[i] + " is python keyword") else: print(keys[i] + " is not a python keyword")
for is python keyword
while is python keyword
Shiksha is not a python keyword
break is python keyword
Devanshi is not a python keyword
