Compatibility

this function is only available on Python 3.6+

the errors argument to Popen is only available on Python 3.6+

the encoding argument to Popen is only available on Python 3.6+

source_hash’ is only available on Python 3.7+. This does not work in lower versions, and therefore is not backwards compatible. Instead, use another hash function.

Found ‘importlib.resources’, which is a module only available on Python 3.7+. This does not work in lower versions, and therefore is not backwards compatible. Use importlib_resources instead for older Python versions.

Found usage of the ‘blocksize’ argument in a HTTPConnection call. This is only available on Python 3.7+ and is therefore not backwards compatible. Remove this in order for this code to work in Python 3.6 and below.

Found usage of the ‘blocksize’ argument in a HTTPSConnection call. This is only available on Python 3.7+ and is therefore not backwards compatible. Remove this in order for this code to work in Python 3.6 and below.

Found usage of ‘importlib.abc.ResourceReader’. This module is only available on Python 3.7+ and is therefore not backwards compatible. Instead, use another loader.

Found usage of ‘importlib.abc.ResourceReader’. This module is only available on Python 3.7+ and is therefore not backwards compatible. Instead, use another loader.

IPv6Network.subnet_of is only available on Python 3.7+ and is therefore not backwards compatible. Instead, check if the subnet is in ‘subnets’.

IPv6Network.supernet_of is only available on Python 3.7+ and is therefore not backwards compatible. Instead, check if the supernet is in ‘supernet’.

IPv4Network.subnet_of is only available on Python 3.7+ and is therefore not backwards compatible. Instead, check if the subnet is in ‘subnets’.

IPv4Network.supernet_of is only available on Python 3.7+ and is therefore not backwards compatible. Instead, check if the supernet is in ‘supernet’.

Found usage of the ‘monetary’ argument in a function call of ‘locale.format_string’. This is only available on Python 3.7+ and is therefore not backwards compatible. Instead, remove the ‘monetary’ argument.

math.remainder is only available on Python 3.7+ and is therefore not backwards compatible. Instead, use math.fmod() or calculate $X - n*$Y.

multiprocessing.Process.close() is only available on Python 3.7+ and is therefore not backwards compatible. Instead, use join().

multiprocessing.Process.kill() is only available on Python 3.7+ and is therefore not backwards compatible. Instead, use terminate().

os.preadv() is only available on Python 3.7+ and is therefore not backwards compatible. Instead, use a combination of os.readv() and os.pread().

os.pwritev() is only available on Python 3.3+ and is therefore not backwards compatible. Instead, use a combination of pwrite() and writev().

pdb.set_trace() with the header argument is only available on Python 3.7+ and is therefore not backwards compatible. Instead, use set_trace() without the header argument.
