Python手寫數字識別之路1

元組字串

格式化字串

序列雖然python是從c語言發展而來，但是我覺得和c語言區別巨大。

首先玩乙個小遊戲

"python"

import random
counts =
3answer = random.randint(1,
10)#生成乙個隨機數，guess
while counts >0:
temp =
input
("enter number "
) guess =
int(temp)
if guess == answer:
print
("right"
)break
else
:if guess < answer:
print
("small"
)else
:print
("big"
) counts = counts -
1print
("game over"
)

member =

['小明'
,'弱音'
,'狂三'
,'光輝'
]for i in member:
print
(i,len
(i))
for i in
range(0
,20,3
):# 步進為3
print
(i)

while ture:

member =

member.extend(
['東方'
,'**'])
for i in member:
print
(i,len
(i))
member.insert(1,

)for i in member:
print
(i,len
(i))
member.remove(
'手寫數字識別'
)for i in member:
print
(i)del member[1]
for i in member:
print
(i)member.pop(1)
for i in member:
print
(i) 
member[1:
3]for i in member[1:
3]:print
(i)

手寫數字識別

這幾天在想這做字元識別方面的程式，看了很多 但是發現 上的幾乎用處都不是特別的大，理論一大堆，但是用在程式裡面則很難實現，看到有些 上說用連碼法，但是連碼法對結構的變化太敏感了，但是也從一些 裡獲得了一些靈感，我採用的是網格匹配法，準備工作採集樣本，得到了樣本的網格資訊用於接下來的識別，當然也可 一...
