The picture is as follows:


Problem analysis: Look at the picture also do not understand what meaning, so look at the Raiders. The title means: Shift each character two times, for example: K→m
Problem Solving Process:

Import redef CHARSHITF (aa):    p1=re.compile (' [a-x] ')    if P1.match (aa):        return Chr (ORD (AA) +2)    elif AA = = ' Y ':        return ' a '    elif aa = = ' Z ':        return ' B '    else:        return aastraa = "G FMNC wms Bgblr RPYLQJYRC gr ZW fy Lb. rfyrq ufyr amknsrcpq ypc DMP.

Answer: By interpreting the text content of the page: I hope you didnt translate it by hand. Thats what computers is for. Doing it in by hand are inefficient and that's why the this text was so long. Using String.maketrans () is recommended. Now apply to the URL.
In fact, just interpret the map character, MAP→OCR
Experience: The use of regular expressions, reference to the RE.
The whole procedure is not concise enough, and so on, to adjust it.
