只能输入16进制python

A. python为什么中文显示的都是16进制的

你先看是在什么情况下显示16进制的，python不能直接将中文数组，中文列表一次性print的，一个一个print就可以了

B. 如何让python的16进制运算的输出格式为16进制而不是10进制

a='0x0012e'
b=
hex(eval(a))
print
b
输出
0x12e
注意，一般计算机的十六进制数直接输出的时候是不补0的，所以
0x12e
就是
0x0012e，就好像
0005和5在整型数是存储成一样的值。

C. python 16进制问题，如图

'd' == '\x64'，也就是100

D. python怎么让bytes不按照字符显示可显示字符 而是只用十六进制

方法一
>>> array_alpha = [ 133, 53, 234, 241 ]
>>> print ''.join('{:02x}'.format(x) for x in array_alpha)
8535eaf1

方法二
>>> print ''.join(format(x, '02x') for x in array_alpha)
8535eaf1

E. python怎样将16进制转化为2进制

#coding=gbk
var=input("请输入十六进制数：")
b=bin(int(var,16))
print(b[2:])

运行结果

详细请参考python自带int函数、bin函数用法

参考网址：https://docs.python.org/3/library/functions.html?highlight=int#bin

1. classint(x,base=10)
   

Return aninteger object constructed from a number or stringx, or return0if no arguments are given. Ifxis a number, returnx.__int__(). For floating point numbers, this truncates towards zero.

Ifxis not a number or ifbaseis given, thenxmust be a string,bytes, orbytearrayinstance representing aninteger literalin radixbase. Optionally, the literal can be preceded by+or-(with no space in between) and surrounded by whitespace. A base-n literal consists of the digits 0 to n-1, withatoz(orAtoZ) having values 10 to 35. The defaultbaseis 10. The allowed values are 0 and 2–36. Base-2, -8, and -16 literals can be optionally prefixed with0b/0B,0o/0O, or0x/0X, as withinteger literals in code. Base 0 means tointerpret exactly as a code literal, so that the actual base is 2, 8, 10, or 16, and so thatint('010',0)is not legal, whileint('010')is, as well asint('010',8).

Theinteger type is described inNumeric Types — int, float, complex.

Changed in version 3.4:Ifbaseis not an instance ofintand thebaseobject has abase.__index__method, that method is called to obtain aninteger for the base. Previous versions usedbase.__int__instead ofbase.__index__.

Changed in version 3.6:Grouping digits with underscores as in code literals is allowed.

2.bin(x)

Convert aninteger number to a binary string. The result is a valid Python expression. Ifxis not a Pythonintobject, it has to define an__index__()method that returns an integer.

F. python串口16进制问题

显示没错。。1、2、3、4对应的ascii/unicode码位值分别就是31h,32h,33h,34h

转回字符显示可以

print(chr(0x31))#显示"1"
