else :
print ( "x is greater than y" )
>>> %Run -c $EDITOR_CONTENT
x is greater than y
Nested if
We can embed an if statement into another if statement, and then call it a nested if statement.
Example
x = 67
if x > 10 :
print ( "Above ten," )
if x > 20 :
print ( "and also above 20!" )
else :
print ( "but not above 20." )
>>> %Run -c $EDITOR_CONTENT
Above ten,
and also above 20!
3.5.6 While Loops
The
while
statement is used to execute a program in a loop, that is, to execute a program in a loop under certain
conditions to handle the same task that needs to be processed repeatedly.
Its basic form is:
while test expression:
Body of while
In the
while
loop, first check the
test expression
. Only when
test expression
evaluates to
True
, enter
the body of the while. After one iteration, check the
test expression
again. This process continues until
test
expression
evaluates to
False
.
In MicroPython, the body of the
while
loop is determined by indentation.
The body starts with an indentation and ends with the first unindented line.
Python interprets any non-zero value as
True
. None and 0 are interpreted as
False
.
