Example - Zero padding Zero padding is done by adding a 0 at the start of fieldwidth. print("%015.5f" % 5.1234567890) Output: 000000005.12346 Example - proper alignment For proper alignment, a space can be left blank in the field width so that when a negative number is used, proper align...

print(question) for option in options[question_num]: print(option) python会先执行print("---")然后print(question)以此类推。 2. question_num这个变量的意义 这个quiz game里的question_num = 0,名称叫question_num 或 answer_num并不重要,重要是这个变量作为一个计数的变量,在options[question/answer_...

以结果不match搜索,很快就知道了Python和Node的异同:Node这个decipher比较高级,默认就有auto Padding(对于解码,就是auto unpadding)。这个可以通过decipher.setAutoPadding(false);来取消掉。相对,Python我这个就比较底层,所以要手动unpad: 1 2 3 4 fromCrypto.Util.Paddingimportunpad ...
