Common List Operations

Operation Description
x in s True if element x is in sequence s.
x not in s True if element x is not in sequence s.
s1 + s2 Concatenates two sequences s1 and s2.
s * n, n * s n copies of sequence s concatenated.
s[i] ith element in sequence s.
s[i : j] Slice of sequence s from index i to j – 1.
len(s) Length of sequence s, i.e., the number of elements in s.
min(s) Smallest element in sequence s.
max(s) Largest element in sequence s.
sum(s) Sum of all numbers in sequence s.
for loop Traverses elements from left to right in a for loop.
<, <=, >, >=, =, != Compares two sequences.Compares two sequences.
 >>>list1 = [2, 3, 4, 1, 32]

>>> import random
 >>>random.shuffle(list1) # Shuffle the elements in list1
 >>> list1
