Write a function in Python to read a text file, Alpha.txt and displaysthose lines which begin with the word ‘You’

Sure! Here's a step-by-step guide to writing a Python function that reads a text file and displays lines that begin with the word 'You':

1. Define the function and give it a meaningful name, such as 'display_lines_starting_with_you'.

2. Inside the function, open the text file using the 'open' function and assign it to a variable, let's say 'file'.

3. Use a 'for' loop to iterate over each line in the file. You can use the 'readlines' method to read all the lines at once and store them in a list.

4. Within the loop, use an 'if' statement to check if the line starts with the word 'You'. You can use the 'startswith' method to perform this check.

5. If the line starts with 'You', print the line using the 'print' function.

6. After the loop, close the file using the 'close' method to free up system resources.

7. Test the function by calling it and passing the name of the text file as an argument.

Here's the complete code:

def display_lines_starting_with_you(file_name):
    file = open(file_name, 'r')
    lines = file.readlines()
    for line in lines:
        if line.startswith('You'):
            print(line)
    file.close()

# Test the function
display_lines_starting_with_you('Alpha.txt')

Make sure to replace 'Alpha.txt' with the actual name of your text file.
