print()
x='abc'
print(x.center(10,"*"))
print(x.ljust(10,'*'))
print(x.rjust(10,'*'))
print(x.zfill(10))
print()
x='123'
print(x.zfill(10))
x=123
print(str(x).zfill(10))
print()
x='phone_number'
print(x.isidentifier())
x='222test'
print(x.isidentifier())
print()
x=' '
print(x.isspace())
x='\n'
print(x.isspace())
print()
x='python is fun'
table=x.maketrans('thon','1234')
print(x.translate(table))
2.实验任务2
程序源代码
x = [5, 11, 9, 7, 42]
print('整数输出1: ', end = '')
i = 0
while i < len(x):
print(x[i], end = ' ')
i += 1
print('\n整数输出2: ', end = '')
i = 0
while i < len(x):
print(f'{x[i]:02d}', end = '-')
i += 1
print('\n整数输出3: ', end = '')
i = 0
while i < len(x) - 1:
print(f'{x[i]:02d}', end = '-')
i += 1
print(f'{x[-1]:02d}')
print('\n字符输出1：',end = '')
y1 = []
i = 0
while i < len(x):
y1.append(str(x[i]))
i += 1
print ('-'.join(y1))
print('字符输出2：',end = '')
y2 = []
i = 0
while i < len(x):
y2.append(str(x[i]).zfill(2))
i += 1
print('-'.join(y2))
3.实验任务3
#把姓名转换成大写
#方法1
name_list = ['david bowie','louis armstrong','leonard cohen','bob dylan','cocteau twins']
i = 0
while i < len(name_list):
print(name_list[i].title())
i += 1
print()
#方法2
t = []
i = 0
while i < len(name_list):
t.append(name_list[i].title())
i += 1
print('\n'.join(t))
4.实验任务4
程序源代码
name_list1 = ['david bowie', 'louis armstrong', 'leonard cohen', 'bob dylan', 'cocteau twins']
name_list1.sort()#按字母排序
num = 0
for i in name_list1:
num += 1
print(num, end = '.')
print(i.title())
if num >=len(name_list1):#如果大于人头数就停止
break
5.实验任务
程序源代码
import this
#导入 Zen of Python到字符串中
str1 = "".join([this.d. get(c,c) for c in this.s])
print("行数：",str1.count('\n'))
print("单词数：",len(str1.split()))
print("字符数：",len(str1))
print("空格数：",str1.count(' '))
6.实验任务
程序源代码
book_list = [['静静的顿河','肖洛霍夫','金人', '人民文学出版社'],
['大地之上','罗欣顿.米斯特里','张亦琦', '天地出版社'],
['夜航西飞', '柏瑞尔.马卡姆', '陶立夏', '人民文学出版社'],

['灯塔','克里斯多夫.夏布特','吕俊君','北京联合出版公司'],
['小行星掉在下午','沈大成', '', '广西师范大学出版社']]
t = '图书信息'
print(t.center(40,"*"))
for t in range(0,len(book_list)):
print(t+1,end='.')
print('|'.join(book_list[t]))
7.实验任务7
程序源代码
data = ['99 81 75', '30 42 90 87', '69 50 96 77 89 93', '82 99 78 100']
list1=[]
k=0
for i in data:
list1=list1+i.split(' ')
for i in range(len(list1)):
k+=int(list1[i])
print("%.2f"%(k/len(list1)))
运行结果
8.实验任务8
程序源代码
words_sensitive_list = ['张三', 'V字仇杀队', '杀']
comments_list = ['张三因生命受到威胁正当防卫导致过失杀人，经辩护律师努力，张三不需负刑事责任。',
'电影<V字仇杀队>从豆瓣下架了',
'娱乐至死']
k=[]
for i in range(0,len(comments_list)):
