Python3字符串到文件中的十六进制错误但在终端中没有

Question

this is my piece of code which outputs at input clues[0] = '706965':

x = clues[0]
answer = bytes.fromhex(x).decode("ascii")

<class 'ValueError'>, ValueError('non-hexadecimal number found in fromhex() arg at position 5')

If I add 0 to to clues[0] it outputs the expected output with first char with offset.

x = '0'+clues[0]

The output then is '[]ie'. The [] means special char(stackoverflow ommits it).

but if i run this example in terminal everything works fine.

>>> x = '706965'
>>> bytes.fromhex(x).decode("ascii")
'pie'

Solved: Parsing error

Answer 1

From the docs for bytes.fromhex

This bytes class method returns a bytes object, decoding the given string object. The string must contain two hexadecimal digits per byte, with ASCII whitespace being ignored.

Prepending '0' to your string makes it length seven, so it can't consist of two-digit pairs
