Hangman
今天在看别人python博客的时候，发现了博主对python学习的介绍，分享了几个有趣的python网站。 其中有一个是Full Stack Python，里面介绍很多关于python的使用手册，覆盖面很广，但是好像主要是在web development上面的。 虽然自己真的很想学习Python的web framework，但是感觉还是想先dive into data structure之中。Web Framework以后有时间再学吧。
知乎上面有一个关于python博客和阅读资源的回答，感觉很有帮助，发现原来真的有这么多的python使用者，以及用它做着pretty cool的事情。 Python 有哪些好的学习资料或者博客？
不扯这些了。之前看到了给Python新手准备的五个迷你项目，刚好今晚没什么事情，就尝试了一下。
Five mini programming projects for the Python beginner
前四个mini project都很简单，也不免有些无聊，但是也为自己复习了一下最基础的python，比如说a = raw_input()，input一个3，type(a)应该是str… 当时也傻了半天
代码先贴一下， Dice Rolling Simulator ——-
"""
This is for a mini project that generate random integer between 1 and 6
"""
from random import randint
def rolling_dice():
n = randint(1,6)
print n
def main():
rolling_dice()
while True:
a = raw_input('Do you want to roll dice again? Y/N')
if a == 'y' or a == 'Y':
rolling_dice()
else:
break
main()Guess the number
from random import randint
def capture():
try:
a = int(raw_input('This is a number between 1 to 100, please guess'))
except ValueError:
print 'you should type a integer'
capture()
def main():
answer = randint(1,100)
a = capture()
count = 1
while True:
if a < answer:
a = int(raw_input('too low, guess again'))
count += 1
elif a > answer:
a = int(raw_input('too high, guess again'))
count += 1
elif a == answer:
print 'That\'s right!, the right answer is %d, you only take %d steps' %(a, count)
break
main()Hangman
"""
This project is to create a sort of "guess the word" game.
"""
def main():
answer = raw_input('please type the word')
# dic save all the letters of the answer
dic = {}
num_of_word = 0
for i,n in enumerate(answer):
num_of_word += 1
dic[i] = n
all_times = 0
place = {}
for n in range(num_of_word):
place[n] = None

times = 0
DRAW = False
for n in dic:
if dic[n] == guess_word:
place[n] = guess_word
times += 1
DRAW = True
if not DRAW:
print 'guess again'
all_times = all_times + times
if DRAW:
draw_word(place)
if all_times == num_of_word:
break
def draw_word(dic):
for i in dic:
if dic[i] == None:
print '_',
else:
print dic[i],
if __name__ == '__main__':
main()值得一提的是最后一个mini project，简单是很简单，但是自己一开始做的时候却忘记了dictionary直接把位置和字母匹配， 结果写了一段很奇怪的draw_word()，这里也po上来吧，免得以后自己再犯这种奇怪的错误。
def draw_word2(letter, place, num_of_word, times):
"""
an example of place
0, 1, 2 is the occuring times of the letter
place = {0 : 1, 1 : 3, 2 : 6}

string = []
for i, n in enumerate(place):
if n == 0:
string.append('_ '*place[n]+letter)
else:
string.append('_ '*(place[n] - place[n - 1] - 1) + letter)
r_word = ''
for i, n in enumerate(string):
r_word += string[i]
r_word += ' '
r_word = r_word + ' _'*(num_of_word - place[times-1] -1)
print r_word##Life is short, You need Python.
顺便Po个算法题，下次有空写。
