month="一月份二月份三月份四月份五月份六月份七月份八月份九月份十月份十一月十二月"
for i in range(12):   #插入循环，可循环12次
                      n=eval(input("请输入你要转换的月份（1-12）："))
　　　　　　pos=(n-1)*3
　　　　　　print("{}月份是{}".format(n,month[pos:pos+3]))

2. Continued upward every day. Although every day, but the human development capacity is not infinite, it is consistent with a particular model. Capacity growth in line with assumptions

As model with plateau: 7-day cycle, continuous learning ability value unchanged three days, starting from day 4 to day 7 day capacity growth

1% the previous day. If you have a seven day break to learn, the period ab initio. Please write a program to answer, if the initial capacity value

1, continuous learning value of 365 days is how much?

3. Analyzing palindrome. Let n is an arbitrary natural number, if a reverse arrangement of n digits of the resulting natural number equal to n, then n is called palindrome. From the keyboard

Enter a 5-digit number, please write a program to determine this number is not a palindrome.

Code:

while(1):

n=input("请输入一个五位数：")
if len(n)==5:
if n[::-1]==n:
print(n+"是一个回文数")
else:

print(n+"不是回文数")
else:
print("输入不符合要求")

operation result:
