In this code, shown also in Figure 5-11, you can see in bold text the Python words
while True:
added before the user input question, and
break
added within the
conditionals for left and right. he
while True:
condition will loop the question
over and over until the player enters either
left
or
right
so that the game does not
end if the player types anything else.

Using a
while
loop in the Python adventure game
A
Indentation
refers to how far from the margin a line of code is typed. Indentation
of code in Python is very important, especially when you begin to add more
structure to your code by using conditionals and loops. In Adventures 3 and 4, you
used conditionals and loops in Scratch. When you added a
forever
loop, you
placed individual blocks inside it. These blocks inside the loop were indented from
the rest of the statement. It is similar in Python. After you type
while True
: the
next line should be indented, otherwise your code may not work. The same is
true of the conditionals
if
,
else
and
elif
.
