Python Practice

Iterate over a list in Python

for val in a:

    print(val)

Using for Loop with range()

n = len(a)

 

# Iterates over the indices from 0 to n-1 (i.e., 0 to 4)

for i in range(n):

    print(a[i])

Using while Loop

# Start from the first index

i = 0

 

# The loop runs till the last index (i.e., 4)

while i < len(a):

    print(a[i])

    i += 1

Using enumerate()

# Here, i and val reprsents index and value respectively

for i, val in enumerate(a):

    print (i, val)

Using List Comprehension

left = 0

right = 2

pp = [num_val for i, num_val in enumerate(a) if i >= left and i <= right]
