[英]Reading from a file and assigning content to a variable in Python
我在文本文件中有一個 ECC 鍵值,我想將該值分配給變量以供進一步使用的一組行。 雖然我可以從文件中讀取鍵值,但我不知道如何將值分配給變量。 我不希望它作為一個數組。 例如,
變量 = 讀取(public.txt)。
有關如何執行此操作的任何輸入?
python版本是3.4
# Get the data from the file
with open('public.txt') as fp:
v = fp.read()
# The data is base64 encoded. Let's decode it.
v = v.decode('base64')
# The data is now a string in base-256. Let's convert it to a number
v = v.encode('hex')
v = int(v, 16)
# Now it is a number. I wonder what number it is:
print v
print hex(v)
或者,在 python3 中:
#!/usr/bin/python3
import codecs
# Get the data from the file
with open('public.txt', 'rb') as fp:
v = fp.read()
# The data is base64 encoded. Let's decode it.
v = codecs.decode(v,'base64')
# The data is now a string in base-256. Let's convert it to a number
v = codecs.encode(v, 'hex')
v = int(v, 16)
# Now it is a number. I wonder what number it is:
print (v)
print (hex(v))
