The problem is quite simple. Given a string, we need to replace all commas with dots and all dots with the commas. This can be achieved in two popular ways.
Examples:
Input : 14, 625, 498.002 Output : 14.625.498, 002
Using maketrans and translate()
maketrans: This static method returns a translation table usable for str.translate(). This builds a translation table, which is a mapping of integers or characters to integers, strings, or None.
translate: This returns a copy of the string where all characters occurring in the optional argument are removed, and the remaining characters have been mapped through the translation table, given by the maketrans table.

# Python code to replace, with . and vice-versa def Replace(str1): maketrans = str1.maketrans final = str1.translate(maketrans(', .', '., ')) return final # Driving Code string = "14, 625, 498.002"print(Replace(string)) |
Output:
14.625.498, 002
Using replace()
This is more of a logical approach in which we swap the symbols considering third variables. The replace method can also be used to replace the methods in strings. We can convert “, ” to a symbol then convert “.” to “, ” and the symbol to “.”. For more reference visit Python String Methods.
Example:
def Replace(str1): str1 = str1.replace(', ', 'third') str1 = str1.replace('.', ', ') str1 = str1.replace('third', '.') return str1 string = "14, 625, 498.002"print(Replace(string)) |
Output:
14.625.498, 002
