Python 3.3：十六进制和十进制转换

Question

I'm able to convert Hex data to Decimal with:

file = open("my_text.txt", "r+")
data = input("Type Hex: ")
hex = int(data, 16)
str(hex)
print(str(hex))
file.write(str(hex))
file.close()
input("close: ")

But how can I convert Decimal data, like a number or a sentence, to Hex? Also, is it possible to write data to a hexadecimal offset?

Answer 1

How about something like this?

>>> print(hex(257))
0x101
>>> for ch in b'abc':
...    print(hex(ch))
...
0x61
0x62
0x63

BTW, assigning to a variable called "hex" occludes the built-in function - it's best to avoid that.
