how does a for loop work in python code example

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: for loop python

Python Loops

for x in range(1, 80, 2):
  print(x)

words=['zero','one','two']
for operator, word in enumerate(words):
	print(word, operator)

for x in range(1, 80, 2):
  print(x)

Example 3: for in python

for i in range(1,10,2): #(initial,final but not included,gap)
  print(i); 
  #output: 1,3,5,7,9
  
for i in range (1,4): # (initial, final but not included)
  print(i);
  #output: 1,2,3 note: 4 not included

for i in range (5):
  print (i);
  #output: 0,1,2,3,4 note: 5 not included

python = ["ml","ai","dl"];  
for i in python:
  print(i);
  #output:  ml,ai,dl
  
for i in range(1,5):	#empty loop...if pass not used then it will return error
  pass;

Example 4: python for loop

words=['zero','one','two']
for operator, word in enumerate(words):
	print(word, operator)
