python for loop examples

Example 1: python loops

#x starts at 1 and goes up to 80 @ intervals of 2
for x in range(1, 80, 2):
  print(x)

Example 2: python for loop

#to print number from 1 to 10
for i in range(1,11):
    print(i)

#to print a list
l = [1,2,3,4]
for i in l:
    print(i)

r = ["a","b","c","d","e"]
s = [1,2,3,4,5]

#print two list with the help of zip function
for p,q in zip(r,s):
    print(p,q)

Example 3: for in range loop python

#there are two possibilities for a for loop
#first one is with a range()
#range() just generates lists after the following pattern

print(range(4))
>>> [0,1,2,3]
print(range(1,4))
>>> [1,2,3]
print(range(2,10,2))
>>> [2,4,6,8]

#and what the for does then is that it lets a variable (in my example x) cycle trough the list given after in

for x in range(2,10,2):
  print(x)
>>> 2
>>> 4
>>> 6
>>> 8

#so the code in the loop gets executed for every value in the given list after in
#you can also use for ... in for custom lists
#example 1:

list1 = [1,2,50,2]

for x in list1:
  print(x)

>>> 1
>>> 2
>>> 50
>>> 2

#example 2

list2 = ["bananas", "apples", "pears"]

for x in list2:
  print(x)

>>> "bananas"
>>> "apples"
>>> "pears"

Example 4: python for loop

nums = ['one', 'two', 'three']
for elem in nums:
  print(elem)

Example 5: python for loop

my_list = ["milk", "coffee", "bread"]
# i stands for iterator
for i in my_list:
  print(i) # prints every element of my_list
