TypeError: ‘str’ object cannot be interpreted as an integer [duplicate]

A simplest fix would be:

x = input("Give starting number: ")
y = input("Give ending number: ")

x = int(x)  # parse string into an integer
y = int(y)  # parse string into an integer

for i in range(x,y):
    print(i)

input returns you a string (raw_input in Python 2). int tries to parse it into an integer. This code will throw an exception if the string doesn’t contain a valid integer string, so you’d probably want to refine it a bit using try/except statements.
