关于python列表增加元素的三种操作方法

a = [0,0,0]
b = [1,2,3]
a.insert(0,b)
print a

a = [0,0,0]
b = [1,2,3]
a.extend(b)
print a

[0, 0, 0, 1, 2, 3]

a = [0,0,0]
a.append(1)
print a

[0, 0, 0, 1]

names = ['John','Thomas','Jack','Tony']

print(names)

# 在末尾添加元素

names.append('Bill')
print(names)

['John', 'Thomas', 'Jack', 'Tony']
['John', 'Thomas', 'Jack', 'Tony', 'Bill']

names = ['John','Thomas','Jack','Tony']

print(names)

# 在列表中插入元素


names.insert(0,'Bill')



print(names)

['John', 'Thomas', 'Jack', 'Tony']
['Bill', 'John', 'Thomas', 'Jack', 'Tony']
