我目前正在自学 Python，我只是想知道（参考下面的示例）用简单的术语来说，这 sys.argv[1] 代表什么。它只是要求输入吗？

#!/usr/bin/python3.1

# import modules used here -- sys is a very standard one
import sys

# Gather our code in a main() function
def main():
  print ('Hello there', sys.argv[1])
  # Command line args are in sys.argv[1], sys.argv[2] ..
  # sys.argv[0] is the script name itself and can be ignored

# Standard boilerplate to call the main() function to begin
# the program.
if __name__ == '__main__':
  main()

_{您可能被引导到这里，因为您询问的是使用sys.argv的代码中的IndexError 。问题不在于您的代码；问题在于您需要以使sys.argv包含正确值的方式运行程序。请阅读答案以了解sys.argv工作原理。}

_{If you have read and understood the answers, and are still having problems on Windows , check if Python 脚本是否不采用 Windows 中的 sys.argv 来 fixes the issue. If you are trying to run the program from inside an IDE , you may need IDE-specific help - please search, but first check if you can run the program successfully from the command line.}
