1. Write the code for a python function expand (x) that takes a list of strings, concatenates them, and returns the resulting string repeated three times? 2. As written, the following statement is invalid because it is split across several lines. Modify it so it doesn't raise an exception, using implicit line continuation. s='a' + 'b' + 'c' + 'd' + 'e' + 'f 3. Given the following directory structure: animals/ |----feline/ | |--lions.gif | |----tigers.gif |-----ursine/ | |__bears.gif |__animals.csv Assuming that the cwd is in the root folder where animals resides, what is the full path to the feline folder? 4. Develop an algorithm that adds two three dimensional matrices (one dimensional arrays) 5. Develop a phyton code that prompt the user for a number and password. Then show encrypted output. Using XOR binary 1. Write the code for a python function expand (x) that takes a list of strings, concatenates them, and returns the resulting string repeated three times? 2.
