If you want a string to represent an integer in another number system, then you use a formatted string, such as an f-string (in Python 3.6+), and an option that specifies the base: Python. >>> octal = 0o1073 >>> f"{octal}" # Decimal '571' >>> f"{octal:x}" # Hexadecimal '23b' >>> f"{octal:b}" # Binary '1000111011'.

Since you're writing a calculator that would presumably also accept floats (1.5, 0.03), a more robust way would be to use this simple helper function: def convertStr(s): """Convert string to either int or float.""". try: ret = int(s) except ValueError: #Try float. ret = float(s) return ret.
10 Ιουλ 2020 · In Python an integer can be converted into a string using the built-in str() function. The str() function takes in any python data type and converts it into a string. But use of the str() is not the only way to do so. This type of conversion can also be done using the "%s" keyword, the .format function or using f-string function. Below is the list
