Question

can someone explain how to do this in python? the idea is to figure out the 4 digit code(ex: 3968) entered by the user. how would one design an algorithm to go about finding this?
here is what i got..:

code=int(input("Enter 4 digit secret code:"))
count=0000
while(count!=code):
    count=count+1
print("Your code was",count)

this works perfectly….Except when the code starts with 0… Ex: 0387
it prints ” Your code was 387″ as appose to 0387

whats a quick fix for this?

Answer 1

print("Your code was %04i" % count)

The % means that here comes a variable.
The 04 means zero-pad it to four characters.
The i means it’s an integer. Docs here.

Alternative version, using the new, more flexible .format() formatting:

print("Your code was {:04n}".format(count))
