Homework 1：

Judge "amy" Whether in ["bob","tony","Lisa","Steven"] Inside , If it is, output 'amy In the logical family ', Otherwise output 'amy be not in ... So sad '

analysis ：

The member operator is used

Code ：（ Two kinds of ）

list=["bob","tony","Lisa","Steven"]
if "amy" in list:
    print("amy In the logical family ")

    print("amy be not in ... So sad ")

The ternary operator is used ！

Homework 2：

'ax'<'xa' by True still False？

Why? ？

analysis ：True

The comparison between strings is based on ASCCII Compare the size of

ax Of ASCCII Code is 97,120

xa yes ASCCII Code is 120,97

then ax and xa Compare one by one 97<120, therefore ax<xa

Code ：

print("ax"<"xa")

Homework 3：

If the following procedure is entered 666 Which statement to execute ？ Why? ？

temp=input(' Please enter ：')

if temp == 'Yes' or 'yes':

    print('if Yes ！')

else:

    print('else Yes ！')

analysis ：

perform "if Yes ！"

== and or Than to carry out ==

or：1、 really or really = really         2、 really or false = really         3、 false or false = false

Code ：

temp=input(" Please enter ：")

if temp=="Yes" or "yes":

    print("if Yes ！")

else:

    print("else Yes ！")

Homework 4：

is And == The difference between ？

is Is an identity operator ,== Is a comparison operator , They are all used for comparison , But the comparison values are different ,is Compare memory addresses ,== Is used to compare values

Homework 5：

User input a,b

When a And b Not for 0 Output when a And b Do business ; Otherwise output a And b The product of the

analysis ：

Code ：

a=int(input(" Please enter a Corresponding number ："))
b=int(input(" Please enter b Corresponding number ："))
if a != 0 and b !=0:
    print(a//b)
else:
    print(a*b)

a and b Not for 0 when ：

a and b One side is zero or both ：

Homework 6:

Question based 5, Use the ternary operator to output a,b A larger number

analysis ：

Code ：

a=int(input(" Please enter a Corresponding number ："))
b=int(input(" Please enter b Corresponding number ："))

print(a if a>b else b )

When a>b when                                                                    When b>a when ：
