filecmp.cmp(f1, f2, shallow=True) Compare the files named f1 and f2, returning True if they seem equal, False otherwise. If shallow is true, files with identical os.stat() signatures are taken to be equal. Otherwise, the contents of the files are compared. Note that no external programs are called from this function, giving it portability and efficiency. This function uses a cache for past comparisons and the results, with cache entries invalidated if the os.stat() information for the file c

os.set_handle_inheritable(handle, inheritable) Set the “inheritable” flag of the specified handle. Availability: Windows.

os.stat(path, *, dir_fd=None, follow_symlinks=True) Get the status of a file or a file descriptor. Perform the equivalent of a stat() system call on the given path. path may be specified as either a string or as an open file descriptor. Return a stat_result object. This function normally follows symlinks; to stat a symlink add the argument follow_symlinks=False, or use lstat(). This function can support specifying a file descriptor and not following symlinks. Example: >>> import os

test.support.import_fresh_module(name, fresh=(), blocked=(), deprecated=False) This function imports and returns a fresh copy of the named Python module by removing the named module from sys.modules before doing the import. Note that unlike reload(), the original module is not affected by this operation. fresh is an iterable of additional module names that are also removed from the sys.modules cache before doing the import. blocked is an iterable of module names that are replaced with None i

statistics.median_low(data) Return the low median of numeric data. If data is empty, StatisticsError is raised. The low median is always a member of the data set. When the number of data points is odd, the middle value is returned. When it is even, the smaller of the two middle values is returned. >>> median_low([1, 3, 5]) 3 >>> median_low([1, 3, 5, 7]) 3 Use the low median when your data are discrete and you prefer the median to be an actual data point rather than interpo

operator.__contains__(a, b) Return the outcome of the test b in a. Note the reversed operands.

Wave_write.setcomptype(type, name) Set the compression type and description. At the moment, only compression type NONE is supported, meaning no compression.

clone(**kw) Return a new Policy instance whose attributes have the same values as the current instance, except where those attributes are given new values by the keyword arguments.

ipaddress.collapse_addresses(addresses) Return an iterator of the collapsed IPv4Network or IPv6Network objects. addresses is an iterator of IPv4Network or IPv6Network objects. A TypeError is raised if addresses contains mixed version objects. >>> [ipaddr for ipaddr in ... ipaddress.collapse_addresses([ipaddress.IPv4Network('192.0.2.0/25'), ... ipaddress.IPv4Network('192.0.2.128/25')])] [IPv4Network('192.0.2.0/24')]

ArgumentParser.format_help() Return a string containing a help message, including the program usage and information about the arguments registered with the ArgumentParser.
