我们通常可以使用os模块的命令进行执行cmd
os.system(执行的命令) # 源码 def system(*args, **kwargs): # real signature unknown """ Execute the command in a subshell. """ pass
os.popen(执行的命令)
# 源码
def popen(cmd, mode="r", buffering=-1):
if not isinstance(cmd, str):
raise TypeError("invalid cmd type (%s, expected string)" % type(cmd))
if mode not in ("r", "w"):
raise ValueError("invalid mode %r" % mode)
if buffering == 0 or buffering is None:
raise ValueError("popen() does not support unbuffered streams")
import subprocess, io
if mode == "r":
proc = subprocess.Popen(cmd,
shell=True,
stdout=subprocess.PIPE,
bufsize=buffering)
return _wrap_close(io.TextIOWrapper(proc.stdout), proc)
else:
proc = subprocess.Popen(cmd,
shell=True,
stdin=subprocess.PIPE,
bufsize=buffering)
return _wrap_close(io.TextIOWrapper(proc.stdin), proc)
