Using grep from python console

Using python how can I make this happen?

python_shell$>  print myPhone.print_call_log()  |  grep 555

The only thing close that I’ve seen is using “ipython console”, assigning output to a variable, and then using a .grep() function on that variable. This is not really what I’m after. I want pipes and grepping on anything in the output (including errors/info).

Solution

Python’s interactive REPL doesn’t have grep, nor process pipelines, since it's not a Unix shell. You need to work with Python objects.

So, assuming the return value of myPhone.print_call_log is a sequence:

call_log_entries = myPhone.print_call_log()
entries_containing_555 = [
        entry for entry in call_log_entries
        if "555" in entry]
