List

1. Repetition

The repetition operator enables the list elements to be repeated multiple times.

# repetition of list  

# declaring the list  

list1 = [12, 14, 16, 18, 20]  

# repetition operator *  

L = list1 * 2  

print(L)  

2. Concatenation

It concatenates the list mentioned on either side of the operator.

# concatenation of two lists  

# declaring the lists  

list1 = [12, 14, 16, 18, 20]  

list2 = [9, 10, 32, 54, 86]  

# concatenation operator +  

L = list1 + list2  

print(L)

3. Length

It is used to get the length of the list

# size of the list  

# declaring the list  

list1 = [12, 14, 16, 18, 20, 23, 27, 39, 40]  

# finding length of the list  

len(list1)  

4. Iteration

The for loop is used to iterate over the list elements.

# iteration of the list  

# declaring the list  

list1 = [12, 14, 16, 39, 40]  

# iterating  

for i in list1:   

    print(i)  

5. Membership

It returns true if a particular item exists in a particular list otherwise false.

# membership of the list  

# declaring the list  

list1 = [100, 200, 300, 400, 500]  

# true will be printed if value exists  

# and false if not    

print(600 in list1)  

print(700 in list1)  

print(1040 in list1)  

print(300 in list1)  

print(100 in list1)  

print(500 in list1)
