其中的subprocess.call()则可以调用windows系统cmd命令行执行额外的命令。 在使用subprocess.call()之前,需要保证调用的软件已经添加在系统的环境变量路径中。如GDAL: 我以GDAL中的gdalwarp函数为例 当程序能在cmd中正确运行时,我们才可能使用subprocess.call()调用它。 其次,你需要在python中安装subprocess这个库(好像有...
1 status = os.system("mycmd" + " myarg")2 # becomes3 status = subprocess.call("mycmd" + " myarg", shell=True) Notes: Calling the program through the shell is usually not required. A more realistic example would look like this: 1 try:2 retcode = call("mycmd" + " myarg", s...

status = subprocess.call("mycmd" + " myarg", shell=True) Notes: Calling the program through the shell is usually not required. A more realistic example would look like this: try: retcode = call("mycmd" + " myarg", shell=True) if retcode < 0: print >>sys.stderr, "Child was te...
利用Python调用cmd的方法也有不少,例如os.system和subprocess.call(),本次主要介绍后者。同时也会说明一些避雷的注意事项。 subprocess 模块允许我们启动一个新进程,并连接到它们的输入/输出/错误管道,从而获取返回值。其中的subprocess.call()则可以调用windows系统cmd命令行执行额外的命令。 在使用subprocess.call()之前...

使用Windows 10,我想用subprocess.call()将以下标志从python发送到exiftool.exe: -charset FileName=latin 以下命令行条目工作正常: exiftool -charset FileName=latin -overwrite_original -createdate="1960:05:01 12:00:00" "Tif format EXIF sample\Førskole IMG031.tif" ...
使用标准库自带的subprocess 模块 import subprocess subprocess.call(\'notepad\') subprocess.call(\"C:Program Files (x86)TencentQQBinQQScLauncher.exe\") 以上脚本打本记事本程序。 python 官方文档也推荐些使用此模块来来代替 os.system(): subprocess模块比os.system()函数更加灵活,如支持标准输出,错误输出,状...
You may come across other functions like call(), check_call(), and check_output(), but these belong to the older subprocess API from Python 3.5 and earlier. Everything these three functions do can be replicated with the newer run() function. The older API is mainly still there for backw...
