Recently, I was working on a data analysis project where I needed to process a large CSV file containing financial data. The numbers were formatted with commas as thousand separators (like “1,234.56”), but Python’s float() function wouldn’t accept them directly. This is a common challen...
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(...
Problem Statement: How to fix valueerror: couldnot convert string to float in Python? 🐞 What is “ValueError” in Python? In Python, a value is the information that is stored within a specific object. When you encounter a ValueError in Python, it means that there is a problem with the...
Here, strtof converts the string "3.14159" to a float. The endptr parameter helps detect if conversion occurred. If str equals endptr, no characters were converted. This basic example shows the safest way to use strtof with error checking. Always check the endptr to verify successful ...
