In this tutorial, we are going to learn how to have an empty block in Python using the pass statement. Some times you have to create an empty function or leave a block of code empty. For example, if you want to leave the if block empty, then you have to use the pass keyword to avoid errors. Let's see the samples.
Empty blocks using pass statement
Let's see how to create hollow blocks in the if conditionals.
if True:
pass
else:
print('False')
The if block in the above code is empty and the else block will print False.
Empty function using the pass statement
We define a normal function in python using the def keyword.
def function_name():
But if we do not provide any definition to the function, then we will get the error, like with the above code. We have to put a statement inside the function to avoid the mistakes. See how we do it in Python.
def function_name():
pass
We don't get any errors with the above code.
