1.append 函數(shù)

#2的次方數(shù)#

my_list.append(2**2)

2.注意format函數(shù)的用法

users_list=['Niuniu','Niumei','HR','Niu Ke Le','GURR','LOLO']

for i in users_list:

if i== 'HR':

print( 'Hi, HR! Would you like to hire someone?')

else:

print( 'Hi, {}! Welcome to Nowcoder!'.format(i))

3.重點，打印之間的間隔

學(xué)習(xí)一下print的sep和end的區(qū)別：sep在打印連續(xù)內(nèi)容的時候指定分隔符，而end指定一行的結(jié)束符

fori?in?range(1,16,1):

ifi?==?13:

continue

else:

print(i,end='?')

4.矩陣加法，當n個相同矩陣相加

a=[[1,2,3],[4,5,6],[7,8,9]]

n=int(input())

for x in range(len(a)):

for y in range(len(a[x])):

a[x][y]=a[x][y]*n

print(a)
