微信之初学者：基本的列表操作

Posted 2020-08-20

1.列表举例

print(list(‘hello‘))

2列表元素赋值

x = [1,1,1]
x[1] = 2
print(x)

x = [1,1,1]
x[4] = 3
print(x) #会报错的，由于为一个不存在的元素进行赋值

3删除元素

name = [‘hello‘,‘world‘,‘python‘,‘love‘]
del name[2]
print(name)

    ?    

4分片赋值

name = list[‘python‘]
print(name)
name[2:]  = list(‘ar‘)
print(name)

name = list(‘Perl‘)
name[1:] = list(‘ython‘)
print(name)

numbers = [1,5]
numbers[1:1] = [2,3,4]
print(numbers)     #插入元素

numbers = ?[1,2,3,4,5]
numbers[1:4] = []
print(numbers)#删除元素
