Python filecmp method
Module filecmp is used to compare file directories in shallow or deep mode. Filecmp is part of the python utility module.
filecmp.cmp method is used to compare two file,method by default performs the shallow
Comparison by default is set True, meaning that the file signature size,data modification.both file are compared if their identical signatures are equal consider as same file.
Syntax
filecmp.cmp(file1,file2,shallow=True)
file1: this is file which we have to compare
file2 : this is a file two ,which we have to compare too
Shallow : this is optional it is return the bool value either it will true or false
import filecmp file1 = "C:/Users/ASUS/Desktop/abc.txt" file2 = "C:/Users/ASUS/Desktop/test.txt" comp = filecmp.cmp(file1, file2) print(comp) comp = filecmp.cmp(file1, file2, shallow = False) print(comp)
Output
C:\Users\ASUS\Desktop>python test.py False False
Comparison when Shallow is True
import filecmp
# from filecmp import cmpfiles
dir1 = "C:/Users/ASUS/Desktop/dir1/"
dir2 = "C:/Users/ASUS/Desktop/dir2/"
common = ["abc.txt", "test.txt"]
# shallow comparison
match, mismatch, errors = filecmp.cmpfiles(dir1, dir2, common)
# Shallow = True
print("Shallow Comparison")
print("Match: ", match)
print("Mismatch: ", mismatch)
print("Errors: ", errors)
Output
C:\Users\ASUS\Desktop>python cmp.py Shallow Comparison Match: [] Mismatch: [] Errors: ['abc.txt', 'test.txt', 'test2.txt']
Deep Comparison
import filecmp
# from filecmp import cmpfiles
dir1 = "C:\\Users\\ASUS\\Desktop\\dir1\\"
dir2 = "C:\\Users\\ASUS\\Desktop\\dir2\\"
common = ["abc.txt ", "test.txt","test2.txt"]
# shallow comparison
match, mismatch, errors = filecmp.cmpfiles(dir1, dir2, common,shallow=False)
# Shallow = False
print("Deep Comparison")
print("Match: ", match)
print("Mismatch: ", mismatch)
print("Errors: ", errors, "\n\n")
Output
C:\Users\ASUS\Desktop>python cmp.py Deep Comparison Match: [] Mismatch: [] Errors: ['abc.txt', 'test.txt', 'test2.txt']
