Looping a dictionary

Looping a dictionary

Hi,

Trying to understand this piece of code. Would appreciate any help

job_args = dict()

  if args.job_args:

      job_args_tuples = [arg_str.split('=') for arg_str in args.job_args]

      job_args = {a[0]: a[1] for a in job_args_tuples}

So in the first line, we create a dictionary of job_args. Can someone please explain line 3 and 4?

temp_list = []

for arg_str in args.job_args:

    temp_list.append(arg_str.split("="))

job_args_tuples = temp_list

The fourth line is similar, but it is a dict comprehension instead of a list comprehension.

temp_dict = {}

for a in job_args_tuples:

    temp_dict[a[0]] = a[1]

job_args = temp_dict
