逗号变空格

对应攻防世界Misc文件类型

已知有逗号分隔的字符串

50,4B,03,04,14,00,00,00,08,00,09,5D,08,55,EA,3B,0E,DC,28,00,00,00,26,00,00,00,08,00,00,00,66,6C,61,67,2E,74,78,74,4B,CB,49,4C,AF,36,48,4A,4D,36,48,4C,31,4E,49,34,32,34,34,4E,36,37,48,35,35,48,4B,31,35,33,34,4F,B2,48,35,4F,B3,AC,05,00,50,4B,01,02,14,00,14,00,00,00,08,00,09,5D,08,55,EA,3B,0E,DC,28,00,00,00,26,00,00,00,08,00,24,00,00,00,00,00,00,00,20,00,00,00,00,00,00,00,66,6C,61,67,2E,74,78,74,0A,00,20,00,00,00,00,00,01,00,18,00,1B,11,1F,93,D8,AA,D8,01,1B,11,1F,93,D8,AA,D8,01,02,45,FB,8A,D8,AA,D8,01,50,4B,05,06,00,00,00,00,01,00,01,00,5A,00,00,00,4E,00,00,00,00,00

现在要把逗号转换成空格

这里需要用到split方法

split()方法含义：
​
是将指定字符串按某指定的分隔符进行拆分，拆分将会形成一个字符串的数组并返回。

语法
​
split() 方法语法：
​
str.split(str="", num=string.count(str)).
​
参数
​
str -- 分隔符，默认为所有的空字符，包括空格、换行(\n)、制表符(\t)等。
num -- 分割次数。默认为 -1, 即分隔所有。如果参数 num 有指定值，则分隔 num+1 个子字符串

数组中的每元素都各自对应一个索引值，就好比在数据库的表中每行数据纪录都拥有自己的索引ID一样
数组元素的索引值是从0开始计数的，也就是说第一个元素的索引值是0，往后依次加1。

举例：
​
url = 'C://aaa/image/my.jpg'
​
filename = url.split('/')[-1] #以‘/ ’为分割符，为字符串数组，以[-1]为索引，保留最后一段
​
print(filename)
​
结果是：my.jpg
​
​
假如图片的路径为
​
img_path ="aaa\\bbb\\ccc\\cat.0.jpg"
​
label = img_path.split("\\")[-1].split(".'')[0]
​
含义为提取图像绝对路径中，猫或者狗的名cat 或者 dog
​
第一个split(''\\'')[-1]意思是：将整个路径以“\\”分割成字符串数组，[-1]是索引值,取最后一个索引值是cat.0.jpg
​
第二个split(''.'')[0]意思是：将cat.0.jpg 以"."分割成字符串数组 "cat","0","jpg",然后取第0个位置索引，值为cat提取出来

至此 拆分部分的代码就可以写出来了

str="50,4B,03,04,14,00,00,00,08,00,09,5D,08,55,EA,3B,0E,DC,28,00,00,00,26,00,00,00,08,00,00,00,66,6C,61,67,2E,74,78,74,4B,CB,49,4C,AF,36,48,4A,4D,36,48,4C,31,4E,49,34,32,34,34,4E,36,37,48,35,35,48,4B,31,35,33,34,4F,B2,48,35,4F,B3,AC,05,00,50,4B,01,02,14,00,14,00,00,00,08,00,09,5D,08,55,EA,3B,0E,DC,28,00,00,00,26,00,00,00,08,00,24,00,00,00,00,00,00,00,20,00,00,00,00,00,00,00,66,6C,61,67,2E,74,78,74,0A,00,20,00,00,00,00,00,01,00,18,00,1B,11,1F,93,D8,AA,D8,01,1B,11,1F,93,D8,AA,D8,01,02,45,FB,8A,D8,AA,D8,01,50,4B,05,06,00,00,00,00,01,00,01,00,5A,00,00,00,4E,00,00,00,00,00"
s=str.split(",")

再用一个for循环

for i in s：
a = a+i+"\x20"  #\x20在python中代表空格
print(a)

至此拆分和循环代码都写好了 基本代码完成

下面是完整代码

str="50,4B,03,04,14,00,00,00,08,00,09,5D,08,55,EA,3B,0E,DC,28,00,00,00,26,00,00,00,08,00,00,00,66,6C,61,67,2E,74,78,74,4B,CB,49,4C,AF,36,48,4A,4D,36,48,4C,31,4E,49,34,32,34,34,4E,36,37,48,35,35,48,4B,31,35,33,34,4F,B2,48,35,4F,B3,AC,05,00,50,4B,01,02,14,00,14,00,00,00,08,00,09,5D,08,55,EA,3B,0E,DC,28,00,00,00,26,00,00,00,08,00,24,00,00,00,00,00,00,00,20,00,00,00,00,00,00,00,66,6C,61,67,2E,74,78,74,0A,00,20,00,00,00,00,00,01,00,18,00,1B,11,1F,93,D8,AA,D8,01,1B,11,1F,93,D8,AA,D8,01,02,45,FB,8A,D8,AA,D8,01,50,4B,05,06,00,00,00,00,01,00,01,00,5A,00,00,00,4E,00,00,00,00,00"
s=str.split(",")
a=""
for i in s：
a = a+i+"\x20"  #\x20在python中代表空格
print(a)

运行结果
