Python convert pairs list to dictionary

Question

I have a list of about 50 strings with an integer representing how frequently they occur in a text document. I have already formatted it like shown below, and am trying to create a dictionary of this information, with the first word being the value and the key is the number beside it.

string = [('limited', 1), ('all', 16), ('concept', 1), ('secondly', 1)]

The code I have so far:

my_dict = {}
for pairs in string:
    for int in pairs:
       my_dict[pairs] = int

Answer 1

Like this, Python’s dict() function is perfectly designed for converting a list of tuples, which is what you have:

>>> string = [('limited', 1), ('all', 16), ('concept', 1), ('secondly', 1)]
>>> my_dict = dict(string)
>>> my_dict
{'all': 16, 'secondly': 1, 'concept': 1, 'limited': 1}

Just call dict():

>>> string = [('limited', 1), ('all', 16), ('concept', 1), ('secondly', 1)]
>>> dict(string)
{'limited': 1, 'all': 16, 'concept': 1, 'secondly': 1}

The string variable is a list of pairs. It means you can do something somilar to this:

string = [...]
my_dict = {}
for k, v in string:
  my_dict[k] = v

Make a pair of 2 lists and convert them to dict()

list_1 = [1,2,3,4,5]
list_2 = [6,7,8,9,10]
your_dict = dict(zip(list_1, list_2))
