cmp(f1,f2,shallow=True) - The function takes as input file names for two files and return True if they are equal else False.difflib - Simple Way to Find Out Differences Between Sequences/File Contents using PythonĪs a part of our first example, we'll explain how we can compare two files using cmp() function available from filecmp. ![]() If you are interested in finding the line-by-line differences between two files then please check our tutorial on difflib module which provides that functionality. Please make a NOTE that filecmp compares contents of the file and returns results as boolean values (same or not). The contents of the file are taken from the text of zen of Python ( import this). We have below shown the contents of the files. The contents of all original*.txt, modified*.txt is same. We have created a directory structure with a list of files inside it which will be used for various comparison examples that we'll explain as a part of this tutorial.ĭirectory1_1 file2.txt original.txt modified.txtĭirectory1_1_1 original1_1.txt modified1_1.txtĭirectory1_1_1 original.txt modified1_1.txt file2.txtīoth directories have almost the same structure with the same file names in some subdirectories and different in some. As a part of this tutorial, we'll explain how we can use filecmp module for performing different kinds of comparisons with simple and easy-to-understand examples. The module provides different methods to compare two files, more than two files, different directories containing a list of files, etc. To solve that problem and save the time of the developers, Python has developed a module named filecmp which lets developers compare files and directories using its easy-to-use API. Many times developers end up writing their own algorithms to do comparisons of these types. ![]() Python developers many times need to compare files in the same directory or different directories when performing tasks like data analysis, machine learning, etc. Filecmp - Compare Files and Directories using Python ¶
