Compare and print different lines of files with the same name from two different directories-CodePudding

I am writing a script to compare and print files in two different directories.

But I also want, to compare the contents of files with the same names and print any different lines. For example:

cd1
txt1.txt
txt2.txt

cd2
txt1.txt
txt2.txt
txt3.txt

cd1\txt1.txt contains:

line1
line2
line3
line4
line6

while cd2\txt1.txt contains:

line1
line2
line3
line5

I want to be able to print something like:

"Lines in cd1\txt1.txt different than cd2\txt1.txt are: line4 and line6"
"Lines in cd2\txt1.txt different than cd1\txt1.txt are: line5"

My code so far:

########## COMPARE DIRECTORIES ####################

import sys, os

files1 = []
files2 = []

#path1 = input("Please enter the first directory: ")
#path2 = input("Please enter the second directory: ")

path1 = r"C:\Users\Desktop\WBM_V3_events_translated" 
path2 = r"C:\Users\Desktop\WBM_V3_events_blocked"

for path, subdirs, files in os.walk(path1):
    for name in files:
        files1.append(name)
        
for path, subdirs, files in os.walk(path2):
    for name in files:
        files2.append(name)

    print(os.path.join(path2, name))
   
   
distinct_files = []

for file in files2:
    if file not in files1:
            distinct_files.append(file)
            
print("                          ")
print("Printing the files in FOR_TRANSLATION dir, NOT IN the returned TRANSLATED fir. Total:", len(distinct_files))
print("                          ")
for name in distinct_files:
    print(os.path.join(path2, name))

x = 0
y = 0

lines_3 = []
lines_4 = []

for name in files1:
    for line in name:
        lines1.append(line)
        x  = 1
       
for name in files2:
    for line in name:
        lines2.append(line)
        y  = 1

        if line not in lines2:
            if not line.isspace():
                lines_3.append(line)
                
for line in lines2:
        if line not in lines1:
            if not line.isspace():
                lines_4.append(line)

print("                          ")
print("Lines in AAAAAAAAA. Total:", x)
print("                          ")
print(lines_3)

print("                          ")
print("Lines in ZZZZZZZZZ. Total:", y)
print("                          ")
print(lines_4)

The bottom last print statements result in:

Lines in AAAAAAAAA. Total: 103

[]

Lines in ZZZZZZZZZ. Total: 180

['C', 'E', 'r']

CodePudding user response：

I think you should start by creating a method that takes two strings of text and compares them line by line. At the moment, things are getting a little muddled.

For example files1 is a list of file names:

files1 = []
for path, subdirs, files in os.walk(path1):
    for name in files:
        files1.append(name)

but you seem to want to then use files1 as if it was more like a list of file contents:

for name in files1:
    for line in name:
        lines1.append(line)
        x  = 1

In the prior code block, line is a character in the current name, not the contents of the file. You want to look to open() the file by name and read it

for name in files1:
    with open(name, "rt") as file_in:
        for line in file_in:
            lines1.append(line)
            x  = 1
