I am extremely new to python 3 and I am learning as I go here. I figured someone could help me with a basic question: how to store text from a CSV file as a variable to be used later in the code. So the idea here would be to import a CSV file into the python interpreter:
with open('some.csv', 'rb') as f:
reader = csv.reader(f)
for row in reader:
w = ["csv file text"]
print (list(itertools.permutations(["w"], 2)))
itertools.permutations() wants an iterable (e.g. a list) and a length as its arguments, so your data structure needs to reflect that, but you also need to define what you are trying to achieve here. For example, if you wanted to read a CSV file and produce permutations on every individual CSV field you could try this:
import csv with open('some.csv', newline='') as f: reader = csv.reader(f) w =  for row in reader: w.extend(row) print(list(itertools.permutations(w, 2)))
The key thing here is to create a flat list that can be passed to
itertools.permutations() - this is done by intialising
w to an empty list, and then extending its elements with the elements/fields from each row of the CSV file.
Note: As pointed out by @martineau, for the reasons explained here, the file should be opened with
newline='' when used with the Python 3 csv module.
