我想寫一個Python代碼與使用命令行提示的另一個軟件進行交互。執行命令行提示後，目錄中會生成多個輸出文件，並且軟件會使用這些輸出文件進行一些計算。另外，我的程序的其餘部分使用這些輸出文件。目前，我跑我的Python代碼，然後在命令行提示符手動輸入，然後但調用我的代碼的休息和工作正常，當我試圖把：subprocess.call（）或subprocess.Popen生成/使用輸出文件
subprocess.call(['sfit4Layer0.py', '-bv5', '-fs'], shell=False)
到我的文件，它不正確執行（不生成輸出文件）。
當我做出上述代碼時，它是自己的個人python代碼，並在我的代碼的第一部分後立即調用它 - 它也工作。
根據我的輸出，我確信問題是這樣的：調用生成多個文件，然後使用這些文件進行計算，但是，它沒有生成正確的文件，因此我的輸出中出現錯誤。所以在某種程度上，它似乎超越了自己：在計算之前不等待輸出文件被生成，但是當我在程序之外單獨運行此命令時，它仍然有效。任何想法爲什麼會發生？
我在做什麼錯？我是否需要指定目錄（輸出文件是否可以放在我的電腦的其他地方）？我需要使用subprocess.Popen嗎？我搜索了互聯網，但我是Python新手（ish），並且徹底難倒了。
歡迎任何建議。謝謝！
編輯：對於那些誰問，這裏是sfit4Layer0.py代碼：
#! /usr/bin/python
##! /usr/local/python-2.7/bin/python
##! /usr/bin/python
##! /usr/bin/python
# Change the above line to point to the location of your python executable
#----------------------------------------------------------------------------------------
# Name:
# sfit4Layer0.py
#
# Purpose:
# This file is the zeroth order running of sfit4. It accomplishes the following:
# 1) Calls pspec to convert binary spectra file (bnr) to ascii (t15asc)
# 2) Calls hbin to gather line parameters from hitran
# 3) Calls sfit4
# 4) Calls error analysis from Layer1mods.py
# 5) Clean outputs from sfit4 call
#
#
# External Subprocess Calls:
# 1) pspec executable file from pspec.f90
# 2) hbin executable file from hbin.f90
# 3) sfit4 executable file from sfit4.f90
# 4) errAnalysis from Layer1mods.py
#
#
#
# Notes:
# 1) Options include:
# -i <dir> : Optional. Data directory. Default is current working directory
# -b <dir/str> : Optional. Binary directory. Default is hard-code.
# -f <str> : Run flags, h = hbin, p = pspec, s = sfit4, e = error analysis, c = clean
#
#
# Usage:
# ./sfit4Layer0.py [options]
#
#
# Examples:
# 1) This example runs hbin, pspec, sfit4, error analys, and cleans working directory prior to execution
# ./sfit4Layer0.py -f hpsec
#
# 2) This example just runs sfit4
# ./sfit4Layer0.py -f s
#
# 3) This example cleans the output file created by sfit4 in directory (/User/home/datafiles/) which is not the current directory
# ./sfit4Layer0.py -i /User/home/datafiles/ -f c

你有沒有檢查是否有如果程序在同一時間運行時仍然在另一個程序中打開，那麼程序不會嘗試打開該文件？ – lu1her
我該如何檢查？或讓它做到這一點？這是我認爲可能是問題 – alli
它取決於你的程序的行爲，如果他們只是使用文件一次確保'file.close（）'之前打開它在一個不同的程序，但如果你必須檢查在不同的程序中同樣的文件我建議你使用共享內存技術 – lu1her
