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!
3.6.6 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.
