Mohan, the Python print() function by default prints a newline '\n' character at the end. This is can be overridden. See the example below:

print("Print each number in the sequence on a different line")
for x in range(10):
    print(x)

print("Now, print on the same line with dashes in between")

for x in range(10):
    print(x,end='-')

When we run the code, we get this output.

if he did loop through a string how does python program know to print each individual letter on a new line? or is that how python comes?

This might be what you are looking for...

Normally the Python 3 print function prints on a single line (with a newline at the end), but you can change the "end" parameter and substitute your own parameter. I am using a space character in the example below.

# Python 3 code for printing 
# Team Treehouse Is Tops!

print("Team", end=" ") 
print("Treehouse", end=" ") 
print("Is", end=" ")
print("Tops!")
