You can traverse the items in a list with Python's for loop construct. The traversal can be done, using list as an iterator or with the help of index.
Syntax
Python list gives an iterator object. To iterate a list, use the for statement as follows −
for obj in list: . . . . . .
Example 1
Take a look at the following example −
lst = [25, 12, 10, -21, 10, 100] for num in lst: print (num, end = ' ')
Output
It will produce the following output −
25 12 10 -21 10 100
Example 2
To iterate through the items in a list, obtain the range object of integers "0" to "len-1". See the following example −
lst = [25, 12, 10, -21, 10, 100] indices = range(len(lst)) for i in indices: print ("lst[{}]: ".format(i), lst[i])
Output
It will produce the following output −
lst[0]: 25 lst[1]: 12 lst[2]: 10 lst[3]: -21 lst[4]: 10 lst[5]: 100
