python之list和tuple类型1. python创建listl = [‘adam’, 95.5, ‘lisa’, 85, ‘bart’, 59]
print l2. python按照索引访问listl = [95.5,85,59]
print l[0]
print l[1]
print l[2]
print l[3]3. python之倒序访问listl = [95.5, 85, 59]
print l[-1]
print l[-2]
print l[-3]
print l[-4]4. python之添加新元素l = [‘adam’, ‘lisa’, ‘bart’]
l.insert(2, ‘paul’)
print l5. python从list删除元素l = [‘adam’, ‘lisa’, ‘paul’, ‘bart’]
l.pop(3)
l.pop(2)
print l6. python中替换元素l = [‘adam’, ‘lisa’, ‘bart’]
l[0] = ‘bart’
l[-1] = ‘adam’
print l7. python之创建tuplet = (0,1, 2, 3, 4, 5, 6, 7, 8, 9)
print t8. python之创建单元素tuplet = (‘adam’,)
print t9. python之“可变”的tuplet = (‘a’, ‘b’, (‘a’, ‘b’))
print t
