Using the Python programming language you can use int() function to convert string value to int numeric value. This function takes two parameters: the initial string and the optional base to represent the data. As such, you may also use the Python int function as follows: class int(x, base=10) That means you may provide base value for conversion as well. 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. With int() The int function takes in parameters and converts it to integers if it is already a number.
