In python, integer cannot be concatenated with string directly. integer needs to be converted to string for concatenating. str function provided in python can be used to convert integer to string

Example

print(str(50) + ' Balloons')

Output

50 Balloons

When the concatenation is performed with string conversion, following exception is thrown

print(50 + ' Balloons')

Output

TypeError: unsupported operand type(s) for +: 'int' and 'str'
