Convert Strings to Numbers and Numbers to Strings in Python
In Python, strings or numbers can be converted to a number of strings using various inbuilt functions like str(), int(), float(), etc. Let’s see how to use each of them.
Example 1: Converting a Python String to an int:

Python3
# code# gfg contains string 10gfg = "10"# using the int(), string is auto converted to intprint(int(gfg)+20) |
Output:
30
Example 2: Converting a Python String to float:
Python3
# codegfg = "10"# float(gfg) gives 10.0print(float(gfg)+2.0) |
Output:
12.0
Example 3: Converting a Python int to a String:
This is achieved by using str() function as shown below
Python3
# codegfg = 100# str(gfg) gives '100'print(str(gfg)+" is a 3 digit number")# concatenation is performed between themprint(str(gfg)+"200") |
Output:
100 is a 3 digit number 100200
Example 4: Converting a Python float to a String
This is achieved by using str() function as shown below
Python3
# codegfg = 20.0# str(gfg) becomes '20.0'print(str(gfg)+"is now a string")# no addition is performed. concatenated outputprint(str(gfg)+"30.0") |
Output:
20.0is now a string 20.030.0
