TypeError: cannot concatenate 'str' and 'int' objects

integer, printing, python, string

Solution

There are two ways to fix the problem which is caused by the last `print` statement.

You can assign the result of the `str(c)` call to `c` as correctly shown by @jamylak and then concatenate all of the strings, or you can replace the last `print` simply with this:

print "a + b as integers: ", c  # note the comma here

in which case

str(c)

isn't necessary and can be deleted.

Output of sample run:

Enter a: 3
Enter b: 7
a + b as strings:  37
a + b as integers:  10

with:

a = raw_input("Enter a: ")
b = raw_input("Enter b: ")
print "a + b as strings: " + a + b  # + everywhere is ok since all are strings
a = int(a)
b = int(b)
c = a + b
print "a + b as integers: ", c

Problem

I have this python program that adds strings to integers: ``` a = raw_input("Enter a: ") b = raw_input("Enter b: ") print "a + b as strings: " + a + b a = int(a) b = int(b) c = a + b str(c) print "a + b as integers: " + c ``` I get this error: ``` TypeError: cannot concatenate 'str' and 'int' objects ``` How can I add strings to integers?
