getchar - diffrent of Python readline() and C getc()

Answer 1

You can try the f.read(size) function. If size is set to 1, it will read character by character, and then filter the data.

Answer 2

This is easy to usepython, but the result is the same, it’s because your posture is not right

For example, the content you filtered> twiiiiiii@2, 我模拟一下, 假如待处理的文件(raw.dat) is as follows

> t我w爱i北i京i天i安i门ii@2

Up code

with open("raw.dat", "rb") as fh:
    line = fh.readline()
    print(line)
    print(line.decode('ascii', 'ignore'))

Output

b'> t\xce\xd2w\xb0\xaei\xb1\xb1i\xbe\xa9i\xcc\xeci\xb0\xb2i\xc3\xc5ii@2'
> twiiiiiii@2

So there’s no problem, it’s no different from what you use C
