Python work day05

First, a list of store

　　Plot the following two lists in memory of how to store

l1=[11,22,[333,444]]

l2=[11,22,[33,{'name':'egon','age':18}]]

Second, the interaction with the user

　　1, the user enters the name, age, work, hobbies, and then printed in the following format

'''------------ info of Egon -----------
Name  : Egon
#Age   : 22

'''
name_of_user = input('请输入您的名字：')
age_of_user = input('请输入您的年龄：')
sex_of_user = input('请输入您的性别：')
job_of_user = input('请输入您的工作：')
begin = '------------ info of Egon -----------\n'
end = '------------- end -----------------\n'
output_name = 'Name:{Name}\n Age{age}\n sex:{sex}\n job：{job}\n'.format(Name=name_of_user, age=age_of_user,sex=sex_of_user, job=job_of_user)
print(begin, output_name, end)

　　

　　2, the user enters the account password, the program is determined separately account and password are correct, the correct output True, False error output can be

info_user = {
    'Lance1': '123',
    'Lance2': '123',
    'Lance3': '123',
    'Lance4': '123',
    'Lance5': '123',

}
user_name = input("请输入您的账号：")
user_pwd = input("请输入您的密码：")
if user_name in info_user:
    if user_pwd == info_user.get(user_name):
        print(True)
    else:
        print(False)
else:
    print(False)

　　

　　3, make a note of the computer in advance egon at the age of 18 years, wrote a program before age requires user input to guess the age, and the program got egon age and the age of the user input, and outputs a result of the comparison can be

age_of_egon = 18
age_of_input = input("请猜测egon的年龄并输入：")
if age_of_egon == age_of_input:
    print("恭喜您,您的猜测是正确的！！")
else:
    print("很遗憾,您的猜测是错误的！！")

Third, the related operator　　

　　1, taken from the database program 10000 data, intends to display the page, but a page display up to 30 data, please select the appropriate arithmetic operators, calculations show that over 30 pages of data a total of how many? Finally, a few display data?

sql_data = 10000
page = sql_data // 30
last_data = sql_data % 30
print('显示满30条数据的页面总共有{num}个\n最后一页显示{data}条数据\n'.format(num=page, data=last_data))

　　　

　　2, egon this year is 18 years old, please assign computing egon teacher after 3 years of age incremental

age_of_egon = 18
age_of_egon += 3
print('计算3年后egon老师的年龄是：{age}'.format(age=age_of_egon))

　　　

　　3, the one-time value 10 is assigned to the variable names x, y, z

x = y = z = 10　

　　

　　4, add the following values ​​related to the corresponding variable name that it should, you know

dsb = "egon"
superman = "alex"
dsb, superman = superman, dsb
print(dsb, superman)

　　　

　　5, we just want to extract out sucker list, disposable assigned to the corresponding variable name to

names = ['alex_sb', 'wusir_sb', 'oldboy_sb', 'egon_nb', 'lxx_nb', 'tank_nb']
x, y, z, *_ = names
gather = [x, y, z]
print(gather)
