Explanation / Answer

1)
Code:
#!/usr/local/bin/python3

# script name: createSen.py
# create senate file Senate114.txt from Senate113.txt and RetiredSen.txt

def main():
sen = {}
# opening the Senate113.txt in read to store in dictionary sen
with open("Senate113.txt") as fp:
for line in fp:
line = line.strip()
name = line.split(',')[0]
sen[name] = line
fp.close()
  
# opening the file RetiredSen.txt to compare Senate file and delete the entries common in both as some of them are retired
with open("RetiredSen.txt") as fp:
for line in fp:
line = line.strip()
name = line.split(',')[0]
if name in sen and line == sen[name]:
del sen[name]
fp.close()

sen_list = []
# storing into list the dictionary of Senator file
for name in sen:
fields = sen[name].split(',')
sen_list.append(fields)
# sorting the list by state
sen_list_sorted = sorted(sen_list, key=lambda x: (x[1]))

# writing to new file Senate114.txt the sorted list
fout = open("Senate114.txt", "w")
for item in sen_list_sorted:
name, state, pa = item
print(name+","+state+","+pa, file=fout)
fout.close()

if __name__=='__main__':
main()

Execution and output:
Unix Terminal> python3 createSen.py
Unix Terminal>

2)
Code:
#!/usr/local/bin/python

# program to determine number of senators of each party
# script name: numSenator.py

def main():
# opening the file Senate114 for reading
with open("Senate114.txt") as fp:
num_sen = {}
for line in fp:
line = line.strip()
# getting name, state, pa from the file
name, state, pa = line.split(',')
# assigning key the appropriate value based on pa code
if pa == 'I':
key = 'Independents'
elif pa == 'R':
key = 'Republicans'
elif pa == 'D':
key = 'Democrats'
# counting how many Independents, Republicans and Democrats are available
if key in num_sen:
num_sen[key] += 1
else:
num_sen[key] = 1
fp.close()
# printing the final output
print "Party Affiliations:"
for pa in num_sen:
print " " + pa + ":" + str(num_sen[pa])

if __name__=='__main__':
main()

Execution and output:
Unix Terminal> python numSenator.py
Party Affiliations:
Independents:2
Republicans:42
Democrats:43
Unix Terminal>

NOTE: Due to lack of time i was not able to complete the last 2 which i will share the code by EOD today.
