Convert Python String to Float datatype Last Updated : 17 Aug, 2020 Comments Improve Suggest changes Like Article Like Report Let us see how to convert a string object into a float object. We can do this by using these functions : float() decimal() Method 1: Using float() python3 # declaring a string str1 = "9.02" print("The initial string : " + str1) print(type(str1)) # converting into float str2 = float(str1) print("\nThe conversion of string to float is ", str2) print(type(str2)) # performing an operation on the float variable str2 = str2 + 1 print("The converted string to float is incremented by 1 : ", str2) Output : The initial string : 9.02 <type 'str'> The conversion of string to float is 9.02 <type 'float'> The converted string to float is incremented by 1 : 10.02 Method 2: Using decimal() : Since we only want a string with a number with decimal values this method can also be used. python3 # importing the module from decimal import Decimal # declaring a string str1 = "9.02" print("The initial string : " + str1) print(type(str1)) # converting into float str2 = Decimal(str1) print("\nThe conversion of string to float is ", str2) print(type(str2)) # performing an operation on the float variable str2 = str2 + 1 print("The converted string to float is incremented by 1 : ", str2) Output : The initial string : 9.02 <type 'str'> The conversion of string to float is 9.02 <type 'float'> The converted string to float is incremented by 1 : 10.02 Comment More infoAdvertise with us Next Article Convert Python String to Float datatype S shivanshsaxena1 Follow Improve Article Tags : Python python-basics Practice Tags : python Similar Reads Convert String to Float in Python The goal of converting a string to a float in Python is to ensure that numeric text, such as "33.28", can be used in mathematical operations.
