What are the ways to traverse a list in Python?

There are several ways to traverse a list in Python:

##1. For loop traversal

lists = ["m1", 1900, "m2", 2000] for item in lists: print(item)

lists = ["m1", 1900, "m2", 2000] for item in lists: item = 0; print(lists)

Run result:

['m1', 1900, 'm2', 2000]

2. While loop traversal:

lists = ["m1", 1900, "m2", 2000] count = 0 while count < len(lists): print(lists[count]) count = count + 1

3. Index traversal:

for index in range(len(lists)): print(lists[index])

4. Use iter()

for val in iter(lists): print(val)

5. enumerate traversal method

for i, val in enumerate(lists): print(i, val)

Running results:

0 m1 1 1900 2 m2 3 2000

When traversing elements starting from non-0 subscripts, you can use the following method

for i, el in enumerate(lists, 1): print(i, el)

Running results:

1 m1 2 1900 3 m2 4 2000
