How to use the float function in Python?

In Python, the float() function is used to convert other data types into floating-point numbers. For example, you can convert integers into floating-point numbers, as well as convert numbers represented as strings into floating-point numbers.

Here are some examples of how it can be used:

1. Convert integers to floating-point numbers.

num = 10
float_num = float(num)
print(float_num)

1. Convert a string to a floating point number.

str_num = "3.14"
float_num = float(str_num)
print(float_num)

1. Incorrect value

str_num = "abc"
try:
    float_num = float(str_num)
except ValueError:
    print("Invalid float value")

It is important to note that the float() function automatically removes leading and trailing spaces when converting a string.
