Question

Each time Kevin re-reads his Python book (which happens every month), he learns 10% of whatever material he didn’t know before. He needs to score at least 95% on his final to get an A in the class. When Kevin started, he knew nothing about Python. Write a function getLearningTime(rate, target) that simulates Kevin’s learning progress and returns the number of months it will take him to get ready.

Answer 1

Python code:

#defining getLearningTime function
def getLearningTime(rate,target):
    #initializing notLearned as 100
    notLearned=100
    #initializing number of months as 0
    months=0
    #looping till he have learned atleast upto target
    while((100-notLearned)<=target):
        #incrementing months
        months+=1
        #updating notLearned
        notLearned=notLearned-notLearned*0.1
    #returning months
    return months
#calling getLearningTime time for rate 10 and target 95 and printing result
print(getLearningTime(10,95))
