replacing any character that is not 'l', 'r', 'j', 's'

Question

I am creating a script that translates certain characters with directions, and any character that is not one of the known characters is replaced with \"Aaaaah!\".

Answer 1

Use dict and dict.get:

my_dict = {'r': 'right', 'l': 'left', 'j': 'jump', 's': 'straight'}

# string = input('Terrain: ')
string = 'rljsZ' # For test purpose

new_string = ''.join(map(lambda x:my_dict.get(x, 'Aaaaah!'), string))
print(new_string)

Output:

'rightleftjumpstraightAaaaah!'
