Could not convert string to float Python

In this Python tutorial, we will discuss how to fix an error, “Could not convert string to float Python“.

Could not convert string to float python

In python, to convert string to float in python we can use float() method. It can only convert the valid numerical value to a floating point value otherwise it will throw an error.

Example:

my_string = '1,400'
convert = float(my_string)
print(convert)

After writing the above code (could not convert string to float python), Ones you will print ” convert ” then the output will appear as a “ ValueError: could not convert string to float: ‘1,400’ ”.

Here, we get the error because the value is not valid and we used a comma. You can refer to the below screenshot could not convert string to float python.

To solve this ValueError: could not convert string to float we need to give the valid numerical value to convert my string to float by using float() method.

Example:

my_string = '23.8'
convert = float(my_string)
print(convert)

After writing the above code (could not convert string to float python), Ones you will print ” convert ” then the output will appear as a “ 23.8 ”. Here, the float() method converts the string to float. You can refer to the below screenshot could not convert string to float python.

This is how to fix could not convert string to float python.

Example:

str = "Hi"
print(float(str))

The normal text is not supported by the float() function in python. You can refer to the below screenshot for the error.
