Convert String to Double in Python3 Last Updated : 08 Oct, 2021 Summarize Comments Improve Suggest changes Share Like Article Like Report Given a string and our task is to convert it in double. Since double datatype allows a number to have non -integer values. So conversion of string to double is the same as the conversion of string to float This can be implemented in these two ways 1) Using float() method Python3 str1 = "9.02" print("This is the initial string: " + str1) # Converting to double str2 = float(str1) print("The conversion of string to double is", str2) str2 = str2+1 print("The converted string to double is incremented by 1:", str2) Output: This is the initial string: 9.02 The conversion of string to double is 9.02 The converted string to double is incremented by 1: 10.02 2) Using decimal() method: Since we only want a string with a number with decimal values this method can also be used Python3 from decimal import Decimal str1 = "9.02" print("This is the initial string: " + str1) # Converting to double str2 = Decimal(str1) print("The conversion of string to double is", str2) str2 = str2+1 print("The converted string to double is incremented by 1:", str2) Output: This is the initial string: 9.02 The conversion of string to double is 9.02 The converted string to double is incremented by 1: 10.02 Comment More infoAdvertise with us Next Article Convert hex string to float in Python S shivanshsaxena1 Follow Improve Article Tags : Python Python-Built-in-functions python-basics Practice Tags : python Similar Reads Convert Decimal to String in Python Python defines type conversion functions to directly convert one data type to another.
