我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用zlib.py()。
def testAFakeZlib(self): # # This could cause a stack overflow before: importing zlib.py # from a compressed archive would cause zlib to be imported # which would find zlib.py in the archive, which would... etc. # # This test *must* be executed first: it must be the first one # to trigger zipimport to import zlib (zipimport caches the # zlib.decompress function object, after which the problem being # tested here wouldn't be a problem anymore... # (Hence the 'A' in the test method name: to make it the first # item in a list sorted by name, like unittest.makeSuite() does.) # # This test fails on platforms on which the zlib module is # statically linked, but the problem it tests for can't # occur in that case (builtin modules are always found first), # so we'll simply skip it then.
