I have been working on this python program for a hour now, and I am trying to figure out what I an doing wrong in the loop. I ha

Alona [7]

Answer:

startingTuition = tuition

print('Tuition for the year of ' + str(year)+ ' is ' + str(tuition));

Explanation:

Required

The correction to the attached program

Some variables are not needed; so, I've removed the redundant variables.

The main error in the program is in the loop;

After the tuition for each year has been calculated, the startTuition of the next year must be set to the current tuition

Write a program that reads a floating-point number from the user and prints "zero", "positive" or "negative"

Lorico [155]

```
#!/usr/local/bin/python3

foo = float( input( "Enter a number: " ) )
if( foo < 0.0 ):
    print( "negative" )
elif( foo > 0.0 ):
    print( "positive" )
else
    print( "zero" )

exit( 0 )
```
