python基础题库100题及答案-100+Python编程题给你练~（附答案）
春节马上就要到了，怎么能让自己在假期里不掉队？今天，营长给大家准备一个项目： 100+ 编程练习，这些题如果能坚持每天至少完成一道，一定可以帮大家轻松 get Python 的编程技能。目前，这个项目已经获得了 2924 Stars，2468 Forks。
首先，这 100+ 练习题根据难易程度分为三个等级：Level 1、2 和 3。下面对如何定义这三个 Level 进行了说明，大家可以结合自身的学习能力和实践经验进行选择。
Level 1：初级。刚入门 Python 或者正在学一些基础课程的同学们。通常包含 1 到 2 个类或函数的问题都可以解决，甚至答案都可能在一些教材中就能找到。
Level 2：中级。已经系统学习过 Python，并且已经有一定的编程背景的同学们，可以解决包含 3 个及以上类或函数的问题，不过这些答案就在教材找不到了。
Level 3：高级：可以用 Python 中非常丰富的各种库、标准包或更高级的技术，结合数据结构和算法，来解决复杂的问题。
其次，每题都有问题描述、提示和解决方案。大家一定要先独立完成，然后再看参考答案哦~
前 25 题中，Q1~5、22~25 都是 Level 1 的难度，Q6~17 为 Level 2，Q18~22 为 Level 3。大家正好利用这五道题学习、巩固一下基础，然后就开始准备挑战自己吧！
下面先给出前五道题，其他的题目大家可以在 Github 上看到~
Question 1 Level 1 Question:
Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5,
between 2000 and 3200 (both included).
The numbers obtained should be printed in a comma-separated sequence on a single line.
Hints:
Consider use range(#begin, #end) method
Question 2 Level 1 Question:
Write a program which can compute the factorial of a given numbers.
The results should be printed in a comma-separated sequence on a single line.
Suppose the following input is supplied to the program: 8 Then, the output should be: 40320 Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Question 3 Level 1 Question:
With a given integral number n, write a program to generate a dictionary that contains (i, i*i) such that is an integral number between 1 and n (both included). and then the program should print the dictionary.
Suppose the following input is supplied to the program: 8 Then, the output should be:
{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
Consider use dict()
Question 4 Level 1 Question:
Write a program which accepts a sequence of comma-separated numbers from console and generate a list and a tuple which contains every number.
Suppose the following input is supplied to the program: 34,67,55,33,12,98 Then, the output should be:
['34', '67', '55', '33', '12', '98']
('34', '67', '55', '33', '12', '98')
Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.
tuple() method can convert list to tuple
答案要点：
Question 5 Level 1 Question:
Define a class which has at least two methods: getString: to get a string from console input
printString: to print the string in upper case.
Also please include simple test function to test the class methods. Hints:
*Solution 1*
l=[] for i in range(2000, 3201):
if (i%7==0) and (i%5!=0):
l.append(str(i)) print ','.join(l)
___________________________________
*Solution 2* def fact(x): if x == 0:
return 1 return x * fact(x - 1)
x=int(raw_input()) print fact(x)
___________________________________
*Solution 3*
n=int(raw_input())
d=dict() for i in range(1,n+1):
d[i]=i*i print d
___________________________________
*Solution 4*
values=raw_input()
l=values.split(",")
t=tuple(l) print l print t
