Positional-Only Arguments

The / symbol is used to make parameters positional-only.

We must pass values based on their position. We cannot use keyword arguments.

Example:

def calculate(a, b, /):
print(a + b)

calculate(10, 20)

Output:

30

Here:

/ is a positional-only separator.

We must pass arguments by position.

calculate(a=10, b=20)

This gives a TypeError because keyword arguments are not allowed for these parameters.
