I'm trying to pass a dictionary between two functions, I don't want there to be a global variable how would one allow for this to happen?
I'm trying to pass the dictionary that is in my "fileProcessing" function into the "swappingKandV_PrintingResults" function without having a global variable being modified.
dictionary = dict()
fileinputname = input("Please Input File Name: ")
try:
filehandling = open(fileinputname)
except:
print("Invalid Entry")
quit()
rawfile = filehandling.readlines()
def fileProcessing(rawfile):
for iteration in(range(len(rawfile))):
rawfile[iteration] = rawfile[iteration].lower()
for line in rawfile:
line.rstrip()
line.split()
for words in line:
letter = words.split()
for iteration in letter:
if iteration.isalpha() :
dictionary[iteration] = dictionary.get(iteration, 0) 1
def swappingKandV_PrintingResults(dictionary):
finalresults = []
for (k,v) in dictionary.items():
newtuple = (v, k)
finalresults.append(newtuple)
finalresults = sorted(finalresults, reverse=True)
for iteration in finalresults:
print(iteration)
fileProcessing(rawfile)
swappingKandV_PrintingResults(dictionary)

You can accomplish this task in 2 ways:
1. Nested Function Call :
If you want to necessarily call 2nd function after 1st, just write -
'swappingKandV_PrintingResults(dictionary)' as the ending line in the fileProcessing function.
2. Accepting Return from 1st and Passing as Argument to 2nd :
As insisted by @Reti43 too, just write -
'return dictionary' as the ending line in the fileProcessing function and replace your last 2 lines of code by -
Dict = fileProcessing(rawfile)
swappingKandV_PrintingResults(Dict)

By making the first function create and return the dictionary. Then pass that returned dictionary to the second function.
fileinputname = input("Please Input File Name: ")
try:
filehandling = open(fileinputname)
except:
print("Invalid Entry")
quit()
rawfile = filehandling.readlines()
def fileProcessing(rawfile):
dictionary = {}
for iteration in(range(len(rawfile))):
rawfile[iteration] = rawfile[iteration].lower()
for line in rawfile:
line.rstrip()
line.split()
for words in line:
letter = words.split()
for iteration in letter:
if iteration.isalpha() :
dictionary[iteration] = dictionary.get(iteration, 0) 1
return dictionary
def swappingKandV_PrintingResults(dictionary):
finalresults = []
for (k,v) in dictionary.items():
newtuple = (v, k)
finalresults.append(newtuple)
finalresults = sorted(finalresults, reverse=True)
for iteration in finalresults:
print(iteration)
swappingKandV_PrintingResults(fileProcessing(rawfile))
From the way you phrased the question, it seems you have some confusion on how to work with passing arguments to functions and how to handle scope. I would suggest having at look at what a variable is in Python to begin with and then what passing it to a function means.
