Python list (or array) – some basic operations.
Initialize list
a = ["1", "2", "3"] print a print str(a)
['1', '2', '3'] ['1', '2', '3']
Env: Python 2.7.18
access ith item
a = ["v1", "v2", "v3", "v4"] if len(a) >= 1: print a[1]
v2
Env: Python 2.7.18
access last item
a = ["v1", "v2", "v3", "v4"] if len(a) >= 1: print a[-1] print a[len(a)-1]
v4 v4
Env: Python 2.7.18
list length/size using len()
Note than len() can also be used to find string size.
a = ["1", "2", "3"] print len(a)
3
Env: Python 2.7.18
