9.4. Modifying Text¶
We can loop through the string and modify it using
find and slice (substring).
Google has been digitizing books. But, sometimes the digitizer makes a mistake and uses 1 for i. The following program replaces
i everywhere in the string. Now you might not want to really replace every
i, but don’t worry about that right now. It uses a
while loop since we don’t know how many times it will need to loop.
You don’t have to replace just one character. You could replace every instance of a word with another word. For example, what if you spelled a word wrong and wanted to change it everywhere?
Can you loop through and encode a string to hide the contents of the message?
The program below decodes an encoded message, but the lines are mixed up. Put the lines in the right order with the right indentation.
Write the code to replace every 0 with o in the given string ‘The 0wl h00ts l0udly’.
