for loop inside if condition

print "Select the action you want to perform(A or B)"
print "(A) uppper case"
print "(B) count number of lines"

option = raw_input("Enter your option(A or B):")

if option.upper() == "A":
    for line in x:
        line = line.upper()

    print line


elif option.upper() == "B":
    for line in x:
        line = line.upper()
        count = count + 1
    print "total lines:", count

else:
    print "incorrect option"
    exit()

When user enters A it prints only one line(last line) in upper case instead of 250 lines.

count works perfectly.

P.S. I have not submitted the first part of code which is for input of file name to be opened.

just indent your print statement as:

if option.upper() == "A":
    for line in x:
        line = line.upper()

        print line

In Python Indentation plays a very important role, by de indenting the print statement(as it was in the given code), the interpreter would consider it outside the for loop and it would be executed only once after the complete execution of for loop.

In order to execute the printstatement at each iteration of the for loop you need to indent it inside the scope of for loop.
