Python: For and While Loop

Python day 19:

Question:
What are the ways to build and print various lists?

Usually, we use For-Loop/While-Loop to do repetitive commands. 

For-loop only iterates a collection of things, A while-loop can iteration as long as the universe. 

Example:
Create a list from 0 to 5.

For Loop Code

for i in range (0,6):
    print ("adding %d to the list" %i)
    elements.append(i)

Output:

adding 0 to the list
adding 1 to the list
adding 2 to the list
adding 3 to the list
adding 4 to the list
adding 5 to the list

n=0 
number=[]
while n <6:
    n=n+1
    number.append(n)
    print("adding %d to the list" %n)

Note: I had to kill the kernel twice when I was running the While-Loop because it is easy to execute as infinite loops.

Summarize:

While-Loop is fancier but more challenging to write.
For- Loop can get the majority of the things done right.

Happy study
