Question

In python give an example of Any line of the input text file that begins with the character # should be considered as a comment line, and must be ignored. Comment lines do not indicate breaks between paragraphs

Answer 1

• In python we can ignore a line by declaring '#' at starting of line .

Eg:- # this line is ignored by python .

• The below code splits the string on a '#'character.this code keeps everything before the split statement .The '1' argument makes split() method that have stop after one splitting. because we are getting the '0th' substring (which is indexed with[ 0]) and prints the remaining lines by ignoring first line that begins with the character '#'.
• Eg:-

• with open("filename") as file:
       for line in file:
           line =line.split('#',1)[0]
           line =line.rstrip()
           #...... rest of your code will be here
