[Tutor] Python help

[IDN3]

To whom it may concern,
I am having a problem solving the below question. I have used every
resource that I could find to help me, but I'm seeing nothing. Can someone
out there please help me understand the below question and learn how to
accomplish this task in Python? I would really appreciate any help that
someone could afford.


*Problem 1:* Write a program that will calculate the problem and stop after
the condition has been met.



a=number of loops (start with zero)

b=a+1

c=a+b



Condition: If c is less than 5, then the loop will continue; else, it will
end.



3. *Problem 2:*Print a string variable that states the number of loops
required to meet the condition for Problem 1.

My attempt below. I used a while loop even though the question is saying
IF/THEN/ELSE. To my knowledge loops in Python have to be while/for. Also,
it seems like the question is missing some direction, but I could be
wrong. Thank you for your help.

a = 0
b = a + 1
c = a + b
while (c < 5):
print(c)
c = c + 1

OK, We won;t give you the solution but we can certainly help you
understand the question and point you in the right direction.

Notice that a is the thing that counts the number of loops.
So you need to increment a inside your loop.
b and c are based on a.

This is a simple bit of math.
You don't need to run the loop to figure out the answer,
just write an equation.

You obviously did not send the whole question.
I don't see any mention of if/then/else?

The two questions are both OK, but i think you missed the bit that said
a was the variable that counted the number of times round the loop.
This is a little bit unusual since normally your while loop test uses
the counting variable (ie. a) but in this case it uses c which is
based on a. But it does demonstrate that the while condition can be more
complex that the basic form.

a = 0
b = a + 1
c = a + b
print(c)
c = c + 1

You need to make a the counter and not c.
You need to recalculate c after changing a.
You need to print the number of loops (a) not c.

Maybe so, but for an arbitrarily weird condition running the loop may be the
way to go. Therefore I would imagine he is being asked to print how many times
that loop ran. So he should just print that value after the loop finishes (i.e
outside the loop).

Actually, the question's "Condition:" section is written in exactly those
terms.

The way I would read your "Cndition:" requirement is that it is describing what
kind of decision must be made every time the loop commences. It is not telling
you to use Pythons "if" statement. So just putting the correct condition at the
top of the "while" loop is what you want.

Oops, so it is. My bad.
