python以16进制打印

⑴ 用python转换浮点数为16进制怎么写比如把34.4536或者-34.4536转成16进制

#-*-coding:utf8-*-
importctypes
defh2f(s):
cp=ctypes.pointer(ctypes.c_longlong(s))
fp=ctypes.cast(cp,ctypes.POINTER(ctypes.c_double))
returnfp.contents.value
deff2h(s):
fp=ctypes.pointer(ctypes.c_double(s))
cp=ctypes.cast(fp,ctypes.POINTER(ctypes.c_longlong))
returnhex(cp.contents.value)
print(f2h(34.4536))
print(h2f(0x40413a0f9096bb99))

⑵ python中想要把字母或数字转为16进制\x30格式并且输出，但是最终显示却还是字母是怎么回事呢

给你一个函数试试。
def str_to_hex(s):
return ' '.join([hex(ord(c)).replace('0x', '') for c in s])

⑶ python我怎么把数组里面的每个字符串转换成16进制数啊

1. 先把字符串转化为数字格式，

2. 再用hex()把十进度数字转化为十六进制数

代码如下：

source=['1','2','3','4']
destination=[]
foriteminsource:
destination.append(hex(int(item)))
print(destination)

输出如下：

['0x1','0x2','0x3','0x4']
