Question

1. Write a function quote() that takes a file as an input file (quotes.txt), searches it looking for the piece of text (i.e., a string) also given as input, and saves quotes containing that text to a file called watchQuotes.txt one quote per line and print to the screen.

>>> quote('quote.txt', 'is')

file quote.txt not found. Exiting program.

>>> quote('quotes.txt', 'is')

>>> 'The price of freedom is eternal vigilance.' Thomas Jefferson

'And so it often happens that an apparently ingenious idea is in fact a weakness which the scientific cryptographer seizes on for his solution.' Herbert Yardley

Instead performing the operations in the console its better to perform it in the file. So the program has been modified for dynamic operations, you can ask the user for different file names and text to search for in the quotes file.

## Code for the required function:

# Function to check the text in the quotes
def quote(file_name, text):
# Handling file not found error using try block
try:
# opening the quotes file in read mode
file = open(file_name, 'r')
# creating an object for the write file
output_file = open('watchQuotes.txt','w')
# iterating through each quote of the file
for quote in file.readlines():
# spliting the quote based on spaces
line = quote.split()
# checking each word of the line with the text
for word in line:
# if word matches the text, printing the quote to console and writing the quote to file
if word.strip(',') == text:
quote = ' '.join(line)+'\n'
output_file.write(quote)
print(quote,end='')
# printing the error message if file not found
except FileNotFoundError:
print('file',file_name,'not found.Exiting program')
exit()

# Asking the user for the file name with quotes
file_name = input('Enter the File Name which contains quotes: ')
text = input('Enter the text to found in the file with quotes : ')

quote(file_name,text)
