Question 1

call signatures

Answer 1

The signature() function in Python, is used to find the signature of a function.

from inspect import signature
#defining our function
def addition(a:int, b:int):
ans= a + b
return ans
#calling our function
print(“The answer is =”,addition(3,5))
#printing the input parameters of the function
sig = signature(addition)
print(sig)
#printing type of a
print(sig.parameters[‘a’])
#printing annotation of b
print(sig.parameters[‘b’].annotation)

The output would be:

The answer is = 8
(a: int, b: int)
a: int
<class ‘int’>

**This function will raise a TypeError if the class of the object or the object type is invalid.
