PYTHON

While loop

TRAINING 1

On the 1st of september 2017 Tom’s grandmother gives him 150€, then, 15€ more the first day of each following month.

We would like to know until how many months Tom will have a sum exeeding 400€.

Write the corresponding program in Python.

TRAINING 2

1/ By using Python, write an algorithm which prints successively all the square numbers lower than 2000.

2/ Modify the previous algorithm so as it prints as well the number of square numbers belonging to this sequence.

Training 1 - solution

S=150

N=0

while S<=400 :

S=S+15

N=N+1

print("Tom has to wait",N,"months")

Training 2 - solution

1/ N=0

while N**2<=2000:

print(N**2)

N=N+1

2/ N=0

while N**2<=2000:

print(N**2)

N=N+1

print("there are",N,"numbers which square is lower than 2000")
