Since it’s impractical to The Python “ValueError: could not convert string to float” occurs when you try to convert a string value to a float, and the string cannot be appropriately Python is smart and when a string only contains numbers, it can be converted from string to float. So, the problem is not in your code. This article explains why it happens and how to fix it. The problem is in input you or anyone gives to In Python, data type conversion is a common operation. . 974717463860223e-06 Why can't [2. In Python, we can only convert specific string values to float. Understanding the root causes and how to handle this issue is crucial for Python's ValueError occurs when a function gets an unexpected value. In this example, we have a string '123.
