Lab Goal : This lab was designed to demonstrate the similarities and differences in a for loop and a while loop.Lab Description
Mandarinka [93]

Answer:

See Explanation

Explanation:

Required:

Use for and while loop for the same program

<u>(1) String Cleaner</u>

#For Loop

name = "I am Sam"

result = ""  

<em>for i in range(0, len(name)):  </em>

<em>    if name[i]!= 'a':  </em>

<em>        result = result + name[i] </em>

print(result)

#While Loop

name = "I am Sam"

result = ""  

<em>i = 0 </em>

<em>while i < len(name): </em>

<em>    if name[i]!= 'a':  </em>

<em>        result = result + name[i] </em>

<em>    i+=1 </em>

print(result)

<u>(2): Common Divisor</u>

#For Loop

num1 = 528

num2 = 60

div = num2

if num1 > num2:

   div = num1

<em>for i in range(2,div):</em>

<em>    if num1%i == 0 and num2%i==0:</em>

<em>        print(i,end = " ")</em>

print()

#While Loop

num1 = 528

num2 = 60

div = num2

if num1 > num2:

   div = num1

i = 2

<em>while i <div:</em>

<em>    if num1%i == 0 and num2%i==0:</em>

<em>        print(i,end = " ")</em>

   i+=1

The iterates statements show the difference in the usage of both loops.

For the for loop, the syntax is:

<em>for [iterating-variable] in range(begin,end-1)</em>

<em>-------</em>

<em>---</em>

<em>--</em>

<em />

For the while loop, the syntax is:

<em>while(condition)</em>

<em>-------</em>

<em>---</em>

<em>--</em>
