Write a program to accept a filename from the user and display all the lines from the file which contain Python comment character '#'.

Let the file "notes.txt" include the following sample text:

Welcome to the Garden of Dreams 
#where the ordinary becomes extraordinary
#the impossible becomes possible.

file_name = input("Enter the filename: ")
file = open(file_name, 'r')
lines = file.readlines()
for line in lines:
    if '#' in line:
        print(line)
file.close()

Output

Enter the filename: notes.txt
#where the ordinary becomes extraordinary
#the impossible becomes possible.
