字符串比较“逻辑” [英] String Compare "Logic"

问题描述

有人可以告诉我为什么下面的字符串比较提供这些结果？

  >1040" = =12000
 True 
>> 1040< =10000
 False 
  

在C和Python中，结果显然是正确的，我只是不知道如何计算结果...

PS：我知道比较字符串不同的长度是你不应该做的，但我仍然想知道上面这些行背后的逻辑;-)

解决方案

1等于1。

0在2之前（因此1040<12000

4在0之后（因此1040>10000）。

Can anybody please tell me why the string comparisons below deliver these results?

>>"1040"<="12000"  
True  
>> "1040"<="10000"  
False

I've tried the string comparison in both C and Python, the result is obviously correct, I just can't figure out how the result is calculated...

P.S.: I know that comparing strings of different length is something you shouldn't do, but I'm still wondering about the logic behind the above lines ;-)

解决方案

"1" is equal to "1".

"0" comes before "2" (so "1040" < "12000").

"4" comes after "0" (so "1040" > "10000").
