I am asked to get a list of non-repetitive numbers. Below is my code and the error is TypeError: ‘int’ object is not iterable on line 7. I don’t get it. Please help.
def remove_duplicates(a): if a == : print() else: b = [a] # build a 'b' list which has the first number in 'a' list a = a.pop(0) # delete the first number in 'a' list for num in a: # iterates from the second number in the input list if num not in b: b.append(num) return b
