Python基础

一、求1-100内的所有数的和

count = 1
sum = 0
while count <= 100:
    sum = sum +count
    count = count + 1
print(sum)    

二、输出1-100内所有的奇数

count = 1
sum = 0
while count <= 100:
    if count%2 == 1:
        print(count)
    count=count+1

三、输入1-100内所有的偶数

count = 1
sum = 0
while count <= 100:
    if count%2 == 0:
        print(count)
    count=count+1

 四、计算1-2+3-4+5-6·····-96+97-98+99

count = 1;
sum = 0
while count < 100:
    if count % 2 == 1:
        sum = sum + count
    if count % 2 == 0:
        sum = sum - count
    count += 1
print (sum)

五、格式化输出

name = input('请输入姓名\n')
age = int(input('请输入年龄\n'))
job = input('请输入工作\n')
hobbie = input('你的爱好\n')
msg = '''----------info of %s----------
Name   : %s
Age    : %d
job    : %s
Hobbie : %s
--------------- end ---------------
''' % (name,name, age, job, hobbie)
print(msg)
