Keywords are special words in Python that are reserved for a specific purpose and cannot be used as a variable name or function name. There are 33 keywords in Python, and they are all in lowercase.
Here is the complete list of keywords in Python:
Here are some examples of how keywords are used in Python:
- The “if” keyword is used to create a conditional statement. This keyword is followed by a condition, and if the condition is True, a block of code will be executed.
- The “for” keyword is used to create a loop. This keyword is followed by a variable and an iterable object, and it will execute a block of code for each item in the iterable object.
- The “def” keyword is used to define a function. This keyword is followed by the function name and any required parameters, and it is used to create a block of code that can be called multiple times throughout the program.
- The “class” keyword is used to define a class. This keyword is followed by the class name and is used to create a template for creating objects.
- And many more….
It is important to remember that you cannot use these keywords as variable names or function names because they are reserved for specific purposes. For example, you cannot define a variable named “and” because it is a keyword in Python.
Here is an example of how you might use some of these keywords in Python:
x = 10 y = 20 if x < y: print("x is less than y") elif x > y: print("x is greater than y") else: print("x is equal to y") for i in range(5): print(i) def add(x, y): return x + y print(add(10, 20))
As you can see, the keywords “if“, “elif“, “else“, “for“, and “def” are all used in this example to control the flow of the program and define a function.
It is important to use these keywords correctly in your Python code to avoid syntax errors and to ensure that your code is easy to read and understand. Always be mindful of the keywords you are using and make sure that you are using them for their intended purpose.
