In Python an strings can be converted into a integer using the built-in int()
function. The int() function takes in any python data type and converts it into a integer.But use of the int()
function is not the only way to do so. This type of conversion can also be done using thefloat()
keyword, as a float value can be used to compute with integers.
Below is the list of possible ways to convert an integer to string in python:
1. Using int() function
Syntax: int(string)
Example:
num = '10' # check and print type num variable print ( type (num)) # convert the num into string converted_num = int (num) # print type of converted_num print ( type (converted_num)) # We can check by doing some mathematical operations print (converted_num + 20 ) |
As a side note, to convert to float, we can use float() in Python
num = '10.5' # check and print type num variable print ( type (num)) # convert the num into string converted_num = float (num) # print type of converted_num print ( type (converted_num)) # We can check by doing some mathematical operations print (converted_num + 20.5 ) |
2. Using float() function
We first convert to float, then convert float to integer. Obviously the above method is better (directly convert to integer)
Syntax: float(string)
Example:
a = '2' b = '3' # print the data type of a and b print ( type (a)) print ( type (b)) # convert a using float a = float (a) # convert b using int b = int (b) # sum both integers sum = a + b # as strings and integers can't be added # try testing the sum print ( sum ) |
Output:
class 'str' class 'str' 5.0
Note: float values are decimal values that can be used with integers for computation.
