# Slurp the whole file and efficiently convert it to hex all at once hexdata = binascii.hexlify(f.read()) 这只会让你得到一个str的十六进制值,但它比你试图做的要快得多。如果你真的想要一串长度为每个字节的十六进制字符串,你可以很容易地转换结果: hexlist = map

>>> hex(42) '0x2a' >>> oct(42) '0o52' 请注意十六进制系统如何利用字母A直通F来扩充可用数字集。其他编程语言中的八进制文字通常以纯零作为前缀,这可能会造成混淆。Python 明确禁止此类文字以避免出错: >>> >>> 052 File "", line 1 SyntaxError: leading zeros in decimal integer literals are not...
Here's the implementation source for the same. Note: In Python 3.7, Constant folding was moved out from peephole optimizer to the new AST optimizer with some change in logic as well, so the fourth snippet doesn't work for Python 3.7. You can read more about the change here....
This chapter deals with Unicode strings, binary sequences, and the encodings used to convert between them.Depending on your Python programming context, a deeper understanding of Unicode may or may not be of vital importance to you. In the end, most of the issues covered in this chapter do ...

A very common idiom in Python for working with file data demonstrates the context manager:with open ( 'data.txt' , 'r' ) as f : data = f . read () This is good syntax because it simplifies the cleanup step where the file handle is closed. Using the context manager means that you...
