python loop through code example

Example 1: python loop through dictionary

dictionary = {52:"E",126:"A",134:"B",188:"C",189:"D"}
for key, value in dictionary.items():
	print(key)
	print(value)

Example 2: python for loop

# Python for loop

for i in range(1, 101):
  # i is automatically equals to 0 if has no mention before
  # range(1, 101) is making the loop 100 times (range(1, 151) will make it to loop 150 times)
  print(i) # prints the number of i (equals to the loop number)
  
for x in [1, 2, 3, 4, 5]:
  # it will loop the length of the list (in that case 5 times)
  print(x) # prints the item in the index of the list that the loop is currently on

Example 3: python loop through dictionary

d = {'x': 1, 'y': 2, 'z': 3} 
for key in d:
    print key, 'corresponds to', d[key]

Example 4: python for loop

//x starts at 1 and goes up to 5 increasing by 2
for x in range(1,5,2):
  print(x)

Example 5: how to make a loop in python

x = 0
while True: #execute forever
	x = x + 1
	print(x)
