Question

Write a Python program to cut out and display just the Preamble (We the People…).

we are trying to pull that line from a text file

Answer 1

filename = input("Enter file name: ")  # ask for file name

try:
    with open(filename, 'r') as f:  # open file to read
        for line in f:  # read file line by line
            line = line.strip()
            if line.startswith('We the People'):  # check if the line starts with 'We the People'
                print(line)  # if so then print the line
except FileNotFoundError:  # if file is not found
    print(filename + " does not exists!")  # print an error
