Python导入精确的hexa值并显示(Python Importing exact hexa value and display)

Python导入精确的hexa值并显示(Python Importing exact hexa value and display)

我有数据结构，我在其中定义了列表。

data_items = [ {"ID":0x0202, "Name":"Country"}, { "ID":0x2007, "Name":"Sports"}]

我想导入完整的'ID'值，包括'0'，例如：

'0202' '2007'

现在打印如下：

'202' '2007'

码：

Input = 1 SMI = data_items[Input-1]['ID'] hex(SMI)[2:]

建议我怎么办？

I have the Data structure where I defined the list.

data_items = [ {"ID":0x0202, "Name":"Country"}, { "ID":0x2007, "Name":"Sports"}]

I want to import complete 'ID' value including '0', like example:

'0202' '2007'

Now it is printing as below:

'202' '2007'

Code:

Input = 1 SMI = data_items[Input-1]['ID'] hex(SMI)[2:]

Suggest me how can I proceed?

最满意答案

hex删除任何前导零。 如果要在字符串中保持4个字符的长度，请尝试使用hex(SMI)[2:].zfill(4) ，它将在前导零处，直到达到指定的长度。

hex removes any leading zeros. If you want to maintain a length of 4 characters in the string, try doing hex(SMI)[2:].zfill(4) where it will ad leading zeros until it reaches the specified length.
