The difference between a Python colon and a comma __python

Notice that the if\while\for (or function definition) statement contains a colon at the end--we tell Python that it follows a block of statements.

Use of--------------colon if guess = = number:
print ' Congratulations, you guessed it. ' # New blocks starts here
Print "(but you don't win any prizes!)" # New blocks ends here
Elif Guess < color= "#ff0000":
print ' No, it is a little higher than ' # Another block
# can do whatever your want in a block ...
Else
print ' No, it is a little lower than '
--------------
def printmax (x, y):
"" Output the maximum number of 2.
2 values must be integers.
x = Int (x) # Convert to integers,
If possible
y = Int (y)
If x > Y:
Print x, ' is maximum '
Else
Print Y, ' is maximum '
Special use of ======== commas
For item in Shoplist:
Print Item,

We use a comma at the end of the print statement to eliminate line breaks that are automatically printed by each print statement. It's a bit ugly, but it's really simple and effective.
