Next() ('gif', '47 49 46 38 37 61') You can refer to the file signatures at http://www. html. [ 35 ] Python Fundamentals Datetime objects Investigators are often asked to determine when a file was deleted, when a text message was read, or the correct order for a sequence of events. Consequently, a great deal of analysis revolves around timestamps and other temporal artifacts. Understanding time can help us piece together the puzzle and further understand the context surrounding an artifact. For this, and many other reasons, let's practice handling timestamps using the datetime module.

Import this As we saw previously, we can use the split() method on a string to convert it into a list. We can also convert a list into a string using the join method. This method follows a string containing the desired common denominator and the list as its only argument. In the following example, we take a list containing two strings and join them into one string where the elements are separated by a comma. "]) This string is really long, It should probably be on two lines. Understanding scripting flow logic Flow control logic allows us to create dynamic logic by specifying different routes of program execution based upon a series of circumstances.

This script ran, as seen in the following screenshot, until it required input from the user. Once the value was entered, the script continued executing and printed the converted timestamp to the console. [ 48 ] Chapter 2 User input Allowing a user input enhances the dynamic nature of a program. It is good practice to query the user for file paths or values rather than explicitly writing this information. Therefore, if the user wants to use the same program on a separate file, they can simply provide a different path, rather than editing the source code.
