python 单向链表

import sys
import random

class employee:
    def __init__(self):
        self.num=
        self.salary=
        self.name=''
        self.next=None

findword=
data=[[None]* for row in range()]

namedata=['Allen','Scott','Marry','Jon', \
          'Mark','Ricky','Lisa','Jasica', \
          'Hanson','Amy','Bob','Jack']

for i in range():
    data[i][]=i+
    data[i][]=random.randint(,)

head1=employee()   #建立第一组链表的头部
if not head1:
    print('Error!! 内存分配失败!!')
    sys.exit()

head1.num=data[][]
head1.name=namedata[]
head1.salary=data[][]
head1.next=None
ptr=head1
for i in range(,):  #建立第一组链表
    newnode=employee()
    newnode.num=data[i][]
    newnode.name=namedata[i]
    newnode.salary=data[i][]
    newnode.next=None
    ptr.next=newnode
    ptr=ptr.next
ptr=head1
print('结果为：')
k=
while ptr!=None: #打印链表的数据
    print('[%2d %6s %3d] => ' %(ptr.num,ptr.name,ptr.salary),end='')
    k=k+
    if k>=:
        print()
        k=
    ptr=ptr.next

输出

结果为：
[   Allen  ] => [   Scott  ] => [   Marry  ] =>
[     Jon  ] => [    Mark  ] => [   Ricky  ] =>
[    Lisa  ] => [  Jasica  ] => [  Hanson  ] =>
[    Amy  ] => [    Bob  ] => [   Jack  ] =>
