Question

(Python)

Write a program which accomplishes the following tasks:

• set a variable to the result of mathematical expression including +, -, * and / and of both Integer and Float values (or variables)
• set a variable to the result of a combination of string values (or variables)
• set a variable to the result of a combination of string, Integer and Float values (you may need to use the type casting functions)
• Using the following variables:
  a = 1.3
  b = 4
  iterations = 7
  • Create a loop which will execute "iterations" times and outputs the result of the following expression:
    a = a * b
  • reset iterations to 7. create a loop which executes 'iterations' times and contains the following expression:
    iterations -= 1
  • reset iterations to a number between 6 and 12. Create a loop which executes 'iterations' times and does the following:
    • if Iterations is even:
      • subtract 0.5 from b (output a and b)
    • if iterations is odd:
      • multiply a by b (output a)
  • Demonstrate a while loop which contains both an if statement and a for loop. Explain your code.

TURN IN

• Submit your source code
• Execution of your program.
• Explanation of what's happening (these could be comments in your code or a separate text submission)

Answer 1

result1 = 3*4+(5.6/2.3)-.4
result2 = 'a'+2*'b'
result3 = 'a'+2*'b'+int(3.5)*'c'
######################
a=1.3
b=4
iterations=7
for i in range(iterations):
a=a*b
#######################
iterations=7
while iterations>0:
iterations-=1
########################
iterations=8
a=1.3
b=4
while iterations>0:
if iterations%2==0:
b-=.5
print('a:',a,'b:',b)
else:
a*=b
print('a:',a,'b:',b)
iterations-=1
