How to use function float in Python? - with practical example

Sure! Here is a script you can use for your video: --- An introduction: The float() function in Python is used to convert a number or a string that contains a number into a floating-point number. This function is particularly useful when you need to perform mathematical operations that involve decimal points. Example 1: Let's convert an integer to a floating-point number. Explaining: 1. First, we define an integer variable. 2. Then, we use the float() function to convert the integer into a floating-point number. 3. Finally, we print the result to see the conversion. Code:
# Define an integer
num = 5

# Convert the integer to a float
num_float = float(num)

# Print the result
print(num_float)

Example 2: Let's convert a string containing a number to a floating-point number. Explaining: 1. We start by defining a string variable that contains a number. 2. Next, we use the float() function to convert the string into a floating-point number. 3. Finally, we print the result to verify the conversion. Code:
# Define a string containing a number
num_str = "3.14"

# Convert the string to a float
num_float = float(num_str)

# Print the result
print(num_float)

By using the float() function in Python, you can easily convert numbers or strings into floating-point numbers for your mathematical operations.
