Python study notes - os module

Directly output system commands to the screen. The command return value obtained by this method cannot be assigned to a variable. The output result will be garbled due to encoding:

<span style="color: #0000ff">import</span><span style="color: #000000"> os

os.system(</span><span style="color: #800000">"</span><span style="color: #800000">ipconfig</span><span style="color: #800000">"</span>)

Store the system commands obtained by execution into the memory, and then read the results in the memory and output them to the screen without garbled characters:

<span style="color: #0000ff">import</span><span style="color: #000000"> os

com </span>= os.popen(<span style="color: #800000">"</span><span style="color: #800000">ipconfig</span><span style="color: #800000">"</span><span style="color: #000000">).read()
</span><span style="color: #0000ff">print</span>(com)

Create a folder in the directory where the executable file is located

<span style="color: #0000ff">import</span><span style="color: #000000"> os

os.makedirs(</span><span style="color: #800000">"</span><span style="color: #800000">makedir</span><span style="color: #800000">"</span>)
