""" map() use a callback function expecting one parameter... wich is called for each item: you don't (and can't) iterate over it ^^ """ # Fixed code: def add_five(x): if x % 5 == 0: return x + 5 nums = range(0,20) result = list(map(add_five, nums)) print(result) # Anyway, you can do it with filter() function to get only list of filtered result: def div5(x): return x % 5 == 0 def add5(x): return x + 5 nums = range(0,20) result = list(filter(div5, nums)) result = list(map(add5, result)) print(result) # or even shortener use reduce() function (wich is in 'functools' module in Python3: from functools import reduce def red5(r,x): if x % 5 == 0: return r + [x+5] else: return r nums = range(0,20) result = list(reduce(red5, nums, [])) print(result) # https://code.sololearn.com/cCEheB1RADvw/
