Python之List和Tuple类型

Python之List和Tuple类型

1. Python创建list

L = ['Adam', 95.5, 'Lisa', 85, 'Bart', 59]
print L

2. Python按照索引访问list

L = [95.5,85,59]
print L[0]
print L[1]
print L[2]
print L[3]

3. Python之倒序访问list

L = [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 L

5. Python从list删除元素

L = ['Adam', 'Lisa', 'Paul', 'Bart']
L.pop(3)
L.pop(2)
print L

6. Python中替换元素

L = ['Adam', 'Lisa', 'Bart']
L[0] = 'Bart'
L[-1] = 'Adam'
print L

7. Python之创建tuple

t = (0,1, 2, 3, 4, 5, 6, 7, 8, 9)
print t

8. Python之创建单元素tuple

t = ('Adam',)
print t

9. Python之“可变”的tuple

t = ('a', 'b', ('A', 'B'))
print t
