100+编程练习帮大家轻松学习Python,春节也要抓紧学习哟~

春节马上就要到了,怎么能让自己在假期里不掉队?今天,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!

前五道题

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
___________________________________
*Solution 5*
class InputOutString(object):
    def __init__(self):
        self.s = ""

    def getString(self):
        self.s = raw_input()

    def printString(self):
        print self.s.upper()

strObj = InputOutString()
strObj.getString()
strObj.printString()Use __init__ method to construct some parameters
