Loops

while

while i < 10:
    print("i =", i)

With break and continue :

while True:
    do_something()
    if condition:
        break
    else:
        continue

for

Equivalent to foreach in C#

myList = [1, 2, 3]

for i in myList:
    print(i)

for “C-Style”

• With range()

list = [0, 5, 4, 3, 5]

# for (int i=0; i<length(list); i++)
for i in range(len(list)):
    print("list element", i, "is :", list[i])

list = [0, 5, 4, 3, 5]

# for (int i=a; i>n; i+=s)
for i in range(a, n, s):
    print("list element", i, "is :", list[i])

• With Enumerate() : returns a list of coupled values containing the list index with its associated element

Example :

my_list = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']

for i, elt in enumerate(my_list):
    print("At index", i, "is", elt)

-> output :

At index 0 is a.
At index 1 is b.
At index 2 is c.
At index 3 is d.
At index 4 is e.
At index 5 is f.
At index 6 is g.
At index 7 is h.
