Question

I am trying to learn python,
I was trying write C/C++ code i used before in python, can anyone help me find whats wrong in this code….

#print 1st for 1 -> st or 2nd for 2 -> nd , etc

x = int(input('Enter a number :'))
temp = x
while temp>0:
    temp = temp % 10

if temp == 1:
    print (x, "st")
elif temp == 2:
    print (x, "nd")
elif temp == 3:
    print (x, "rd") 
else:
    print (x, "th")

and can you suggest few goods books to learn python, for now i was reading the documentation and its not for beginners…and i know C/C++

Answer 1

Let’s see how this:

temp = x
while temp>0:
    temp = temp % 10

works, using an example (x=12345).

temp = 12345
12345>0
temp = 12345%10 = 5
5>0
temp = 5%10 = 5
5>0
temp = 5%10 = 5
...

So it’s an endless loop!

To get the last digit (which is probably what you want) just do this:

temp = x%10
