python print joining an integer(variable) and a string

[lycanickel]

Hello everyone I am of course new to ppython and I am having trouble joining an integer variable and a string without a space in between them. Lets say my variabe was an integer of num = 121 and I wanted to print the proper ending of "st". which would make it 121st how would I go about it? Here is my code it works fine accept for an unwanted space.

num = input("Please enter a number : ")
numin = int(num)
while (num > 100):
    num = num - 100

if num == 1 or num > 20 and num % 10 == 1:
    print  str(numin) ,("st")
elif num % 10 == 2 and num > 20 or num == 2:
    print str(numin), ("nd")
elif num % 10 == 3 and num > 20 or num == 3:
    print str(numin), ("rd")
elif num % 10 == 4 or num % 10 == 5 or num % 10 == 6 or num % 10 == 6 or num % 10 == 6 or num % 10 == 7 or num % 10 == 8 or num % 10 == 9 or num % 10 == 0 or num == 11 or num == 12 or num == 13:
    print str(numin), ("th")

Here is what my ouput looks like, Also if anyone see any syntax errors that I have made feel free to correct me. I don't want to develop bad habits. Thanks in advance
Please enter a number : 121
121 st

================================ RESTART ================================

Please enter a number : 145
145 th
================================ RESTART ================================

Please enter a number : 735
735 th
================================ RESTART ================================

Please enter a number : 32
32 nd
================================ RESTART ================================

Please enter a number : 33
33 rd

In your code, num is a string, and numin is an integer. It means that the arithmetic expressions involving num won't work as expected. The best thing to do is to replace line 2 with num = int(num) and forget about numin. You can even write num = int(num) % 100.

To answer your initial question, you can write print "%dst" % 121, or print "{0}st".format(121) or print str(121) + "st". My preferred way is the format method.

The last elif... in your code could also be replaced by a single else:. It seems to me that if (num % 10 == 1) and (num != 11) would be easier for the reader that num > 20, etc. You could also have a variable r = num % 10 and write if (r == 1) and (num != 11) etc.

Finally, here is an advanced solution

num = int(num) % 100
suffix = dict(enumerate(("st", "nd", "rd"), 1))
s = "th" if num in (11, 12, 13) else suffix.get(num % 10, "th")
print "{0}{1}".format(num, s)
