# This is a sample Python script.
import sys

    # Use a breakpoint in the code line below to debug your script.
    print(f'Hi, {name}')  # Press Ctrl+F8 to toggle the breakpoint.

import sys

def lm_replace(file, fileName):
    f = open(file,"r+")
    content_before = f.read()
    #print(content_before)
    # 将blendNormal 替换为 blendScreen
    content_after = content_before.replace("ADAMS SIM TIME =   1.0100e+02", fileName)
    #print(content_after)
    
    f.seek(0,0)
    f.truncate()    #清空文件，配合seek使用，否则清空的位置不对
    f.write(content_after)
    f.close()

if __name__ == '__main__':
    print("数据文件夹：")
    rawDir = input()
    fileList = os.listdir(rawDir)
    rawDir = rawDir + "\\"
    
    # write data
    for temFile in fileList:

    print_hi('done')

 

pyinstaller -F ***.py

 

一、安装 pyinstaller

　　pip install pyinstaller

二、使用 pyinstaller 命令

 　　pyinstaller -F --icon=my.ico test.py #打包成exe，并设置图标

　　pyinstaller -F -w yourfilename.py #打包成exe,且不包含控制台

 

其他参数：

一般 python GUI编程才用到 打包成exe，讲道理不如.net 的winform好使
