| - | ==== 01. Minor Design Changes ==== | + | ==== 01. [25p] String manipulation ==== |
| - | Our customer wants to make some changes to our design: | + | First, let's familiarize ourselves with Python's string type: |
| - | * Add a header image with our logo at the top | + | * Read a string input from the user's console (hint: ''[[https://docs.python.org/3/library/functions.html#input|input()]]''); next sub-tasks will use this value and apply various string transformations on it; |
| - | * Several candidates are present inside ''public/images/''; | + | * Print the reversed string (e.g., "hello world" => "dlrow olleh"); hint: there are at least 3 built-in ways to do this in a single line of code ;) |
| - | * **Hint:** check out ''style.css'' for existing definitions! | + | * Print the same string in "aLtErNaTe CaSe" (if you're out of ideas, simply use the [[https://docs.python.org/3/tutorial/controlflow.html#for-statements|for loop]]); |
| - | * Change the color (maybe something blue? depends on the image); | + | * Finally: encrypt the given message using [[https://en.wikipedia.org/wiki/Caesar_cipher|Caesar's Cipher]] (aka, shift each of its alphabet letters to ''n'' positions to the: right for encryption, left for decryption); use the number ''17''' for testing! |
| - | * Make the content box have rounded borders (try ''15px''); | + | |
| + | <note> | ||
| + | **Hints for the last subtask:** | ||
| + | * Remember the [[https://www.cs.cmu.edu/~pattis/15-1XX/common/handouts/ascii.html|ASCII Table]]? | ||
| + | * You can use the ''[[https://docs.python.org/3/library/functions.html#ord|ord()]]'' built-in function to get the ASCII code of a character (as ''int''); | ||
| + | * For the reverse process (''int'' to ''str'' character) you have ''[[https://docs.python.org/3/library/functions.html#chr|chr()]]''; | ||
| + | * Don't forget to wrap around when you reach the last letter of the alphabet: ''Z + 1 => A''! | ||
