我想在同一个 Python 模块中编写多个函数,每个函数都是使用 的单独分析测试timeit,以便我可以使用命令行参数来指定要运行的函数。一个天真的例子(profiling.py)是:
import sys
import timeit
def foo():
    setup = """
    import random
    """
    foo_1 = """
    for i in range(1000):
        random.randint(0, 99) + random.randint(0, 99)
    """
    foo_2 = """
    for i in range(1000):
        random.randint(0, 99) + random.randint(0, 99)
    """
    foo_3 = """
    for i in range(1000):
        random.randint(0, 99) + random.randint(0, 99)
    """
    print 'foo_1', timeit.Timer(foo_1, setup).timeit(1000)
    print 'foo_2', timeit.Timer(foo_2, setup).timeit(1000)
    print 'foo_3', timeit.Timer(foo_3, setup).timeit(1000)
if __name__ == '__main__':
    if (len(sys.argv) > 1):
        if (sys.argv[1] == 'foo'):
            foo()
    else:
        print 'Which profiling do you want to run?'
        print 'available:'
        print '    foo'
但是,当我尝试时python profiling.py foo,我收到如下错误:
foo_1
Traceback (most recent call last):
  File "profiling.py", line 32, in <module>
    foo()
  File "profiling.py", line 25, in foo
    print 'foo_1', timeit.Timer(foo_1, setup).timeit(1000)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/timeit.py", line 136, in __init__
    code = compile(src, dummy_src_name, "exec")
  File "<timeit-src>", line 6
    _t0 = _timer()
                 ^
IndentationError: unindent does not match any outer indentation level
我在代码中搜索了通常的空格/制表符缩进错误,但没有找到。因此我想知道是不是因为我timeit在函数中包装了一个测试,这是不允许的?
