python以16進制列印

⑴ 用python轉換浮點數為16進制怎麼寫比如把34.4536或者-34.4536轉成16進制

#-*-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中想要把字母或數字轉為16進制\x30格式並且輸出，但是最終顯示卻還是字母是怎麼回事呢

給你一個函數試試。
def str_to_hex(s):
return ' '.join([hex(ord(c)).replace('0x', '') for c in s])

⑶ python我怎麼把數組裡面的每個字元串轉換成16進制數啊

1. 先把字元串轉化為數字格式，

2. 再用hex()把十進度數字轉化為十六進制數

代碼如下：

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

輸出如下：

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