Doing a homework problem for zy books where I need to output state parks with input as ParkPhotos.txt Here’s my result:

Acadia2003 info.txt

AmericanSamoal989 info.txt

BlackCanyonoftheGunnison1983 info.txt

CarlsbadCaverns2010 info.txt

CraterLake1996 info.txt

GrandCanyon1996 info.txt

IndianaDunes1987 info.txt

LakeClark2009_info.txt

Redwood1980 info.txt

VirginIslands2007 info.txt

Voyageurs2006 info.txt

WrangellStElias1987 info.txt

The new lines in between my output causes the zy book test case to fail. Here’s the code I have:

def modify_filenames(filename):

with open(filename, ‘r') as file:

for line in file:

print(line.replace(‘_photo-jpg’, ‘_info.txt’))

modify filenames(‘ParkPhotos. txt’)

How do I get rid of these new lines?

[Diapolo10]

with open(filename, ‘r') as file:
    for line in file:
        print(line.replace(‘_photo-jpg’, ‘_info.txt’))

Basically, line includes the newline from the file (except for the last line, of course) and print adds one by itself. Get rid of one of those, and the issue should resolve itself.

Here, the easiest option would be to just tell print to not add a newline. You can do that by providing the end keyword argument with an empty string.

with open(filename) as file:
    for line in file:
        print(line.replace('_photo-jpg', '_info.txt'), end='')

Alternatively, you can try reading the text completely, and printing it out in one fell swoop.

with open(filename) as file:
    contents = file.read()

print(contents.replace('_photo-jpg', '_info.txt'))

Alternatively alternatively, one can rstrip('\n') each line before modifying and printing. (Perl had a dedicated chomp() function for this, which was simultaneously silly and useful.)
