一：循环语句

　　1.计算1+2+3+4....+100

　　

count = 1
sum = 0
while count <= 100:
    sum +=count
    count +=1

print("sum =" ,sum)

　　2.计算1+2-3+4..+99

count = 1
sum = 0
# while count <= 100:
#     sum +=count
#     count +=1
#
# print("sum =" ,sum)
while count < 100 :
    if count % 2 == 0:
        sum = sum - count
    else:
        sum = sum + count
    count += 1
print(sum)

　　3.输出一个自我介绍

　　

name = input("请输入你的名字：")
age = int(input("请输入你的年龄："))
job = input("请输入你的工作：")
msg = '''------ info in %s------
Name : %s
Age  : %d
Job  : %s
---------------  end ------------''' %(name,name,age,job)
print(msg)
