How can I add two variable and assign to result variable in Python?

Question

I am very new to python world,Please help me how to concatenate str and int objects.

a = 100
b= 200
c = 'Result ='
print (c + a + b)

Throwing error

>>> print (c + a + b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: cannot concatenate 'str' and 'int' objects

I looking output as, Result = 300

Thank in advance...!!!

it's clearly mentioned, you have to convert `int` to `str` or use like this `print("{0} {1} {2}".format(c,a,b))` — Lokesh Sanapalli, Oct 24 '16 at 09:22
If you are very new, the proper course of action is to keep reading whatever instructional material you're using, rather than immediately ask a question. — TigerhawkT3, Oct 24 '16 at 09:57

this will not give the OP expected result – Roy Holzem Oct 24 '16 at 09:31
this will give something like this "Result = 300". Isn't that the Ashraf asked? – Januka samaranyake Oct 24 '16 at 09:32
Great ..!!! thanks a lot, could you please explain the difference between. print (c + str(a) + str(b)) and print (c + str(a+b)) – Mohamed Ashraf Oct 24 '16 at 09:33

for completeness: `str(int(a + b))` – Roy Holzem Oct 24 '16 at 09:35

a = 100
b = 200
c = 'Result = '
print("{}{}".format(c,a+b))

This format of coding is safe as you can change the string variable any time and you don't need to worry about output.

a = 100
b = 200
c = 'Result = '
print (c, (a + b))

Even simpler!!!

Actually, you might not need c.

a = 100
b = 200
print ('Result = ', (a + b))
