Python学习的第二天

格式化：

name=input("Name")
job=input("Job")
age=input("Age")
hometown=input("hometown")
info=""
------------info of %s --------------
Name: %s
Age: %s
Job: %s
Hometown:%s
------------End -------------------
""%(name,name,age,job,hometown)

print(info)

#s=string
#d=digit
#f=float

流程分支：

score=int(input("score"))
if score >100
print("分数值不能超过100分")
elif score >=90
print("A")
elif score >=80
print("B")
elif score >=70
print("C")
elif score >=60
print("D")
elif score >=0
print("E")
else
print("分数不能低于零")

age=26
user_guess=int(input("your guess"))
if user_guess==age
print("猜对啦")
elif user_guess> age
print("数据猜大了")
else
print("数据猜小了")

While 循环语句

让程序从0打印到100的程序，每循环一次
count=0
while count<=100
print("loop",count)
count +=1

print("--loop is end--")

打印偶数
count=0
while count<=100
if count%2==0
print("loop",count)
count +=1

print("--loop is end--")

第50次不打印，第60-80打印对应值的平方

自己
count=0
while count<=100
if count！=50 and count<60 and count<80
print("loop",count)
else
print("loop",count*count)
count +=1

print("--loop is end--")

老师
count=0
while count<=100
if count==50
pass
elif count>=60 and count<=80
print("loop",count*count)
else
print("loop",count)
count +=1


死循环
count=0
while True:
print("您",count)
count +=1

循环终止语句break 或者continue
break 完全跳出所有循环
continue
count =0
while count<=100
print("loop",count)
if count==5
break
count +=1
print("---out of the loop---")
跳出，中止

count =0
while count<=100
print("loop",count)
if count==5
continue
count +=1
print("---out of the loop---")

后面一直55555.

打印1-5，95-100
count =0
while count<=100
count +=1
if count>5 and count<95
continue
print("loop",count)
作业：
age=26
count=1
while count<=3
age_guess=input("age_guess")
if age_guess=age
break
else
count+=1

print"----game over----"

age=26
count=1
answer="Y"
answer_=input("YorN")
if answer_=answer
count=1
while count<=3
age_guess=input("age_guess")
if age_guess=age
break
else
count+=1
answer_=input("YorN")
else
print"----game over----"
