The filecmp module defines functions to compare files and
directories, with various optional time/correctness trade-offs.
The filecmp module defines the following functions:
||f1, f2[, shallow[, use_statcache]])
- Compare the files named f1 and f2, returning
they seem equal,
Unless shallow is given and is false, files with identical os.stat() signatures are taken to be equal. Changed in version 2.3: use_statcache is obsolete and
Files that were compared using this function will not be compared again unless their os.stat() signature changes.
Note that no external programs are called from this function, giving it portability and
||dir1, dir2, common[, shallow[,
- Returns three lists of file names: match, mismatch, errors.
match contains the list of files match in both directories, mismatch
includes the names of those that don't, and errros lists the names of files
which could not be compared. Files may be listed in errors because the user may
lack permission to read them or many other reasons, but always that the comparison could
not be done for some reason.
The common parameter is a list of file names found in both directories. The shallow
and use_statcache parameters have the same meanings and default values as for filecmp.cmp().
>>> import filecmp
>>> filecmp.cmp('libundoc.tex', 'libundoc.tex')
>>> filecmp.cmp('libundoc.tex', 'lib.tex')
