how to loop through list in python

1list = [1, 3, 6, 9, 12] 
2   
3for i in list: 
4    print(i) 

1list = [1, 3, 5, 7, 9] 
2
3# with index   
4for index, item in enumerate(list): 
5    print (item, " at index ", index)
6    
7# without index
8for item in list:
9  	print(item)

1# Python list
2my_list = [1, 2, 3]

4# Python automatically create an item for you in the for loop
5for item in my_list:
6  print(item)

1thisList = [1, 2, 3, 4, 5, 6]

3x = 0
4while(x < len(thisList)):
5    print(thisList[x])
6    x += 1
7    
8# or you can do this:

10for x in range(0, len(thisList)):
11    print(thisList[x])
12    
13#or you can do this
14
15for x in thisList:
16    print(x)
