How do I write a Python script to execute bash commands Python 3.6?
There are several ways to execute bash commands from a Python script. One common method is to use the subprocess module. Here's an example:
```python import subprocess
Execute a bash command and capture the output
output = subprocess.check_output("ls -l", shell=True)
Print the output
print(output) ```
Another method is to use the os module:
```python import os
Execute a bash command without capturing the output
os.system("ls -l") ```
You can also use the Popen class to execute a bash command and control the process:
```python import subprocess
Create a Popen object
p = subprocess.Popen("ls -l", shell=True, stdout=subprocess.PIPE)
Read the output from the command
output = p.stdout.read()
Print the output
print(output) ```
