Input and output in different data types in Python

There are mainly three data types, namely:
int
float
string


Let's see an example of all of them in this small program:

a = raw_input("Enter a: ")                   # Taking input for first num in string form
b = raw_input("Enter b: ")                   # Taking input for second num string form
print "a + b as strings: %s" % a  + b   # + will concate and will show in string
a = int(a)                                              # Converting in to integer
b = int(b)                                              # Converting in to integer
c = a + b                                              # Adding two integer
print "a + b as integers: %d" % c         # Printing  two integer
a = float(a)                                           # Converting in to float
b = float(b)                                           # Converting in to float
d = a/b                                                  # deriding
print "a / b as float : %f" % d               # printing as float







Output:
Enter a: 100
Enter b: 35
a + b as strings: 10035
a + b as integers: 135
a / b as float : 2.857143
