Error: 'List' object is not callable in map() function

Question

def powerof(num):
    return num**2

number = [1,2,3,4,5,6,7,8]
s = list(map( powerof , number))
print(s)

Error : 'list' object is not callable

Answer 1

You have defined list as a variable earlier in your code.

Do not do this. Call your variable lst or perhaps something more descriptive.

Minimal example to replicate your error:

list = [1, 2, 3]

def powerof(num):
    return num**2

number = [1,2,3,4,5,6,7,8]
s = list(map( powerof , number))
print(s)
