The simplest way to convert a string with commas to a float in Python is by removing the commas first with the string’s replace() method. def comma_to_float(string_value): # Remove commas from the string cleaned_string = string_value.replace(',', '') # Convert to float and return ...
A step-by-step guide on how to convert a string with a comma separator and a dot to a floating-point number in Python.
my_str = '3,14' # ⛔️ ValueError: could not convert string to float: '3,14' my_float = float(my_str) To solve the error, replace the comma , with a period . to make the value a valid floating-point number. main.py my_str = '3,14' my_float = float(my_str.replace(...
float(number.replace(",", "")) The first line creates a string variable called “number” and assigns it the value “1,000.00”. The second line converts the string variable “number” into a float variable by removing the comma characters and returning the result as a float. Decimal num...
