我有一个字符串文件,但其中的字符串代表十六进制值。例如,我的文件中有这种字符串:
1091 A3B7 56FF ...
我不想将它们用作字符串,而是作为十六进制值;然后将十六进制转换为int。
例如:
1091(in string)---> 1091(in hexa)---> 4241 # The int value of 1091 in hexa
所以我在网上看了一下。我尝试了很多不同的方法,例如:
但是没有什么能与我的需要完全吻合,或者根本不起作用。
这是我的代码的一部分:
t = False
i = 0
while t != True and h != True or i <=100: # My way to look each string of my file
file = row[1]
read_byte = file[i]
if read_byte == 'V': #V is the letter in my file which says that it s the data that I want then there is 2 kinds of channel 01 and 02 that interest me
i=i+1
a=i+2
read_bytechannel = file[i:a] #read 2 strings because the channel can be '01' or '02'
if read_bytechannel == '01':
print(read_bytechannel)
i=i+1
a=i+4
read_bytetemp = file[i:a] # Reading 4 strings because the value is the int value of the two hexa.
realintvalue= # (?????????convert the read_bytetemp string value into an hexa value, then into an int from the hexa)
tempfinal = realintvalue/100 # I have to divide by 100 the int value to get the real temperature
t = True # This condition just tell me that I already know the temporary
i = i+1
这是我想要阅读的那种文件:

>>> int('1091', 16)
4241
int
的第二个参数是解释第一个参数的基础。

你可以尝试这样的东西,int with base 16:
>>> my_string = "1091 A3B7 56FF"
>>> map(lambda x:int(x,16), my_string.split())
[4241, 41911, 22271]
或者你可以同时拥有:
>>> map(lambda x:[x,int(x,16)], my_string.split())
[['1091', 4241], ['A3B7', 41911], ['56FF', 22271]]
如果您对lambda
和map
不满意,可以使用列表理解:
>>> [[x,int(x,16)] for x in my_string.split()]
[['1091', 4241], ['A3B7', 41911], ['56FF', 22271]]
