Python中找不到「主」模塊

Question

當我使用指令python filename.py的代碼，我收到以下錯誤，

/Library/anaconda/bin/python: can't find '__main__' module in filename.py

我不知道究竟是怎麼回事錯在這裏。我需要幫助解決這個問題。 我該如何解決這個問題？

SUFFIXES = {1000: ['KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'], 
      1024: ['KiB', 'MiB', 'GiB', 'TiB', 'PiB', 'EiB', 'ZiB', 'YiB']} 

def approximate_size(size, a_kilobyte_is_1024_bytes=True): 
    '''Convert a file size to human-readable form. 

    Keyword arguments: 
    size -- file size in bytes 
    a_kilobyte_is_1024_bytes -- if True (default), use multiples of 1024 
           if False, use multiples of 1000 

    Returns: string 

    ''' 
    if size < 0: 
     raise ValueError('number must be non-negative') 

    multiple = 1024 if a_kilobyte_is_1024_bytes else 1000 
    for suffix in SUFFIXES[multiple]: 
     size /= multiple 
     if size < multiple: 
      return '{0:.1f} {1}'.format(size, suffix) 

    raise ValueError('number too large') 

if __name__ == 「__main__」: 
    print(「Hello World」) 
    print(approximate_size(1000000000000, False)) 
    print(approximate_size(1000000000000))

這是因爲您使用的引號。更改「 s到"小號
