Question
Consider the following python code:
def carDict(data):
d = dict()
for c in data:
if c not in d:
d[c] = 1
else:
d[c] += 1
return d
cars = ['bmw', 'ford', 'toyota', 'ford', 'ford', 'bmw']
tracker = carDict(cars)
1) How would you iteratively print out all the key value pairs in the dictionary tracker, using a loop?

Code a modular program that uses parallel arrays to store loan application credit scores (values generated between 300 and 900), score ratings (poor, fair, good, very good, or exceptional based on credit score) and loan status (approved or declined applications based on credit score). The program must do the following: The program must first ask the user for the number of loan applications that will be in the simulation. This must be done by calling the getNumLoanApplications() function (definition below). After the input of the number of accounts, the program must use loops and random numbers to generate the credit score, score rating, and application result for each loan application in parallel arrays. These arrays must not be declared globally (major error). The following arrays must be declared and populated: creditScores[]…arrow_forward
