Pass statement in Python programming language

One of the reasons for Python's popularity is its simplicity and ease of use. The Pass statement, along with other control structures, helps make Python even more user-friendly. In this tutorial, we will explore the purpose of the Pass statement, its syntax, and different scenarios where it can be used. By the end of this tutorial, you will have a clear understanding of the Pass statement and how to use it effectively in your Python code. So, let's get started!

Pass statement in Python

• Pass statement in python is a statement that does nothing.
• It is usually used as placeholder for the code that we'll write in future.
• For example, suppose we have an if..else statement but we are currently not sure about the logic that we need to insert in the else part.
• If we leave the else part blank that the interpreter will raise an error, hence we need to write at-least one valid python statement.
• This is where pass statement comes in handy.
• pass is a valid python statement yet it does nothing.
• Thus we can write the pass statement to avoid error, and yet skip the main logic for the future.
• pass statement can be used with many python constructs like :
  • Conditional statements.
  • for statement.
  • while statement.
  • functions.
  • classes.
• Code Sample :

for index in range(2):
    print()
    print("This is the outer loop")
    print(f"Value of index = {index}")

    for cnt in range(3):
        pass


print()
print("Coming out of for loop")
print(f"Value of index = {index}")

# Output
# This is the outer loop
# Value of index = 0

# This is the outer loop
# Value of index = 1

# Coming out of for loop
# Value of index = 1
