一、作業內容

笨辦法學python 習題1-10

習題1：

print("hello world！")

print("hello Again")

print("i like typing this.")

print("This is fun.")

print("Yay！printing.")

print("i’d much rather you ’not.")

print('i “said” do not touch this.')

習題2：

# A comment, this is so you can read your program later.

# Anything after the # is ignored by python.

print("I could have code like this.")# and the comment after is ignored.

# You can also use a comment to "disable" or comment out a piece of code:

#print "This won't run."

print("This will run.")

習題3：

print("I will now count my chickens:")

#print("")

print("Hens",25+30//6)

print("Rooters",100-25*3%4)

#//能夠將數字整除，

print("Now I will count the eggs:")

print(3+2+1-5+4%2-1//4+6)

print("Is it true that 3 + 2 < 5 - 7?")

#給出一個判斷5是否小于-2

print(3+2<5-7)

print("What is 3 + 2?",3+2)

print("What is 5 - 7?",5-7)

print("Oh,that's why it's False")

print("How about some more.")

#對判斷只能給出false和true兩種判斷

print("Is it greater?",5> -2)

print("Is it greater or equal?",5>= -2)

print("Is it less or equal?",5<= -2)

習題4：

cars =100

#有100輛車

space_in_a_car =4.0

#每輛車能運輸的次數

drivers =30

#司機= 30名

passengers =90

#乘客= 90名

cars_not_driven = cars - drivers

#沒有司機駕駛的汽車=總汽車-司機人數

cars_driven = drivers

#有司機的汽車= drivers

carpool_capacity = cars_driven * space_in_a_car

#可運輸乘客人次=有司機的汽車*每輛車的運輸次數

average_passengers_per_car = passengers / cars_driven

#平均每輛車上安排乘車人數=乘車人數/有司機的汽車數

print("There are",cars,"cars available.")

#有100輛車可供選擇

print("There are only",drivers,"drivers available")

#只有30個司機可用

print("There will be",cars_not_driven,"empty cars today.")

#今天會有70輛空車

print("We can transport",carpool_capacity,"people today.")

#今天我們可以運送120人

print("We have",passengers,"to carpool today.")

#我們今天有90人的乘車

print("We need to put about",average_passengers_per_car,"in each car")

#我們需要在每輛車上安排3人

#

習題5：

# -- coding: utf-8 --

name ='Zad A. Shaw'

#我的名字

age =35# not a lie

#我的年齡

height =74# inches

#我的高度

weight =180# lbs

#我的體重

eyes ='Blue'

#我的眼睛

teeth ='White'

#我的牙齒

hair ='Brown'

#我的頭發

print("Let's talk about %s."% name)

#讓我們來談談關于某人

print("He's %d inches tall."% height)

#他的身高

print("He's %d pounds heavy."% weight)

#他的體重

print("Actually that's not too heavy.")

print("He's got %s eyes and %s hair."% (eyes,hair))

#變量2個以上需要使用括號括起來

print("His teeth are usually %s depending on the coffee."% teeth)

#this line is tricky,try to get it exactly right

print("If I add %d, %d, and %d I get %d."% (age,height,weight,age + height + weight))
