print(n1)
#Output: [‘c’, ‘o’, ‘m’, ‘p’, ‘u’, ‘t’, ‘e’, ‘r’]
del n1[0]
print(n1)
#Output: [‘o’, ‘m’, ‘p’, ‘u’, ‘t’, ‘e’, ‘r’]
del n1[1]
print(n1)
#Output: [‘o’, ‘p’, ‘u’, ‘t’, ‘e’, ‘r’]
#count starts from 0(zero)
Example:
n=[1,2,3,4,5,6,7,8,9,10]
del n[2]
print(n)
#Output: [1, 2, 4, 5, 6, 7, 8, 9, 10]
del n[4]
print(n)
#output: [1, 2, 4, 5, 7, 8, 9, 10]
del n[7]
print(n)
#Output: [1, 2, 4, 5, 7, 8, 9]
Delete by range:
n=[0,1,2,3,4,5,6,7,8,9,10]
del n[0:2] #elements of position 0 and 1 are deleted
print(“n[0:2]”,n)
#Output: n[0:2] [2, 3, 4, 5, 6, 7, 8, 9, 10]
n=[0,1,2,3,4,5,6,7,8,9,10]
del n[0:3]
print(“n[0:3]”,n) #elements of position 0,1, and 2 are deleted
#Output: n[0:3] [3, 4, 5, 6, 7, 8, 9, 10]
n=[0,1,2,3,4,5,6,7,8,9,10]
del n[0:5]
print(“n[0:5]”,n)
#Output: n[0:5] [5, 6, 7, 8, 9, 10]
n=[0,1,2,3,4,5,6,7,8,9,10]
del n[2:5]
print(“n[2:5]”,n)
#Output: n[2:5] [0, 1, 5, 6, 7, 8, 9, 10]
n=[0,1,2,3,4,5,6,7,8,9,10]
del n[4:8]
print(“n[4:8]”,n)
#Output: n[4:8] [0, 1, 2, 3, 8, 9, 10]
n=[0,1,2,3,4,5,6,7,8,9,10]
print(n)
del n
# delete entire list
print(n)
#Output: error : NameError: name ‘n’ is not defined
Example:
n = [‘p’,’r’,’o’,’b’,’l’,’e’,’m’]
# delete one item
del n[2]
print(n)
# Output: [‘p’, ‘r’, ‘b’, ‘l’, ‘e’, ‘m’]
# delete multiple items
del n[1:5]
print(n)
# Output: [‘p’, ‘m’]
# delete entire list
del n
print(n)
#Output: Error: List not defined
