3. Flow Controls IF IF / ELIF / ELSE IF / ELSE Conditional assignment
x = 4
if x > 0: print("yes")
IF / ELSE
else: print("no")
IF / ELIF / ELSE
x = 4
if x > 2:
print("yes")
elif x > 0:
print("still yes")
else:
print("no")
Conditional assignment
age = 12
name = "Bob" if age > 18 else "Bobby"

4. For Loops Iterate through a list: Iterate x times:
list_of_items = [1,2,3,4]
for item in list_of_items:
print('-> ' + item)
Iterate x times:
x = 4
for j in range(x):
print('number:', x)
Iterate and enumerate (count):
items = ["apple", "orange"]
for j, item in enumerate(items):
print("item {0} is an {1}".format(j+1, item))
-> 1
-> 2
-> 3
-> 4
number: 0
number: 1
number: 2
number: 3
item 1 is an apple
item 2 is an orange

5. print statement skipped for even numbers
Loop Flow Controls
break: breaks out of the smallest enclosing loop
for x in range(2, 6):
if 8 % x == 0:
print 8, 'equals', x, '*', 8/x
break
continue: skips code which follows and continues with the next iteration of the loop:
x = 4
for j in range(x):
if j % 2 == 0:
continue
print j, 'is an odd number'
loop stops after x=2
8 equals 2 * 4
3 is an odd number
print statement skipped for even numbers

6. PASS statement does nothing.
Loop ELSE Clause
ELSE: a loop’s else clause runs when no break occurs
for x in ('a', 'b', 'c', 'd'):
pass
else:
print('loop finished')
PASS statement does nothing.
loop finished

7. Built-In Functions Built-in Functions Definition dict(iterable)
Create a new dictionary
enumerate(sequence, start=0)
Count and iterate through the sequence
eval(expression)
Compiles and immediately evaluates an expression
exec(expression)
This statement supports dynamic execution of Python code.
float(arg), int(arg), str(arg)
Return a float, integer, or string constructed from the argument
hasattr(object, str_arg_name)
Returns true/false whether an attribute exists in an object
list(iterable)
Create a new list

8. Built-In Functions: part 2
Definition
open(name, mode=r)
Open a file
print(objects, sep=' ')
Print objects to the stream file
range(start, stop[, step])
Create lists containing arithmetic progressions
reversed(seq)
Return a reverse iterator. seq
round(number[, ndigits])
Return the floating point value number rounded to ndigits digits
sorted(iterable)
Return a new sorted list from the items in iterable.
zip([iterable, iterable,…])
This function returns a list of tuples
(2 or more dimensional list)
