List Special Operation in Python
We can perform concatenation using + operator, multiplication, or repetition using * and spiting element of the list using [:] .which has been described by the following example.
a=[1,2,3,7,8,1]
del(a)
b=[4,5,6]
c=a+b
print(c)
c=a*3
print(c)
print(a[1:3])
print(a[1:])
print(a[:3])
print(a[-3:-1])
a=[1,2,3,7,8,1]
del(a)
b=[4,5,6]
c=a+b
print(c)
c=a*3
print(c)
print(a[1:3])
print(a[1:])
print(a[:3])
print(a[-3:-1])
