NAME STRUCTURE KIND WHAT IT DOES NOTE
False - boolean boolean expression
True - boolean boolean expression
elif
if condition1:
statement1…
elif condition2:
statement2…
else:
statement3
condition
if the condition1 is true it
executes the statement1, if the
condition2 it executes the
statement2, otherwise it
executes statement3
else
if condition:
statement1…
else:
statement2…
condition
if the condition is true it
executes the statement1,
otherwise it executes
statement2
if
if condition:
statement1
statement2
condition
if the condition is true it
executes the statements
return return value define
it exits the function at that point
and return the results of "value"
class
class
class_name(par
ameters):
define
it defines a class
def
def
function_name(
parameters):
define
it defines a function or method
of a class
parameters can be absent (); you
can have a default parameter if
you use the =
import
import module import
it imports modules that are not
built-in
break break iteration
interrupts a loop when a a
specific condition occurs
it's used with "while" and "for"
continue continue iteration
move to the next loop iteration
when a specific contition occurs
it's used with "while" and "for"
for
for variable in
[a,b,c…]:
statement1
statement2…
iteration
it creates a loop controlled by a
counter
it executes the statements for
each value of the variable included
in the sequence
while
while condition:
statement1
statement2…
iteration
it executes the statements as
long as the condition is true
if the loop is infinite use "while
True" and then and "if"+condition
with "break"
and x and y operator
it returns true if both x and y are
true
in
x in y operator
it checks if an element is in a
sequence or container
is x is y operator
it checks that 2 objects are the
same in memory
if you just have to check the
equality use ==
not not x operator if returns true if x is false
or x or y operator
it returns true if either x or y is
true
pass pass other
acts as a marker for the code
which is going to be completed,
avoiding that incomplete
constructs return an error
when we want to test the program
or go along with the next
statements, without concluding a
certain part
del del object other
it deletes an object or part of an
object
its common use is to remove
indexes from a list or dictionary
try … except
try:
