python入门-列表

列表使用[]来标识

列表和PHP中的数组类似 包括使用和访问方式都是类似

可以用下标索引的方式直接访问

来几个例子，这样看起来才舒服

names = ['baker','pitty','david','philp']
print(names[0])
print(names[1].title())
print(names[-1])

message = "hello,nice to meet you "+names[0].title()+"."
print(message)

ways = ['bike','moto','car','walk']
info = "I would like to go to company by "+ways[0].title()+"."
print(info)

 插入和删除列表

ways.append('mobike')
print(ways)

ways.insert(0,'hello')
print(ways)

del ways[0]
print(ways)

last=ways.pop()
print(last)
print(ways)

ways.remove('car')
print(ways)

 

使用sort()对列表进行永久性的排序

cars = ['byd','shangqi','mazida','jili']
cars.sort()
print(cars)

cars.sort(reverse=True)
print(cars)

cars = ['byd','shangqi','mazida','jili']
print(sorted(cars))

cars.reverse()
print(cars)

print(len(cars))

print(cars[-1])
