Reserved keywords

Some variable names are not allowed because Python uses them with other special meanings (reserved keywords). In other cases, some variable names cannot be accepted because they contain forbidden symbols or start by a number.

Try to create variables with the following names:

miles, Test, a+b, ba, 4#R, $4, #44, apps, if, elif, x, y, radius

For example:

miles=10

a+b=10

b-a=10

Then say whether the identifier is accepted or not as a variable name.

Identifier	Accepted Yes/No and reason:
miles
Test
a+b
ba
4#R
$4
#44
apps
if
elif
x
y
radius
