I need a jolt here with my python excercise, please somebody!! How can I
make my functions work correctly? I tried below but I get the following
error:
if f_dict[capitalize]:
KeyError: <function capitalize at 0x00AE12B8>
Code below:
def capitalize (s):
"""capitalize accepts a string parameter and applies the capitalize()
method"""
s.capitalize()
def title(s):
"""accepts a string parameter and applies the title() method"""
s.title()
def upper(s):
"""accepts a string parameter and applies the upper() method"""
s.upper()
def lower(s):
"""accepts a string parameter and applies the lower() method"""
s.lower()
def exit():
"""ends the program"""
import sys
sys.exit()
if __name__ == "__main__":
f_dict = {'capitalize': 'capitalize(s)',
'title': 'title(s)',
'upper': 'upper(s)',
'lower': 'lower(s)',
'exit': 'exit(s)'}
options = f_dict.keys()
prompt = 'Enter a function name from the list (%s): ' % ',
'.join(options)
while True:
inp = input(prompt)
option =f_dict.get(inp, None)#either finds the function in question or
returns a None object
s = input ("Enter a string: ").strip()
if not (option):
print ("Please enter a valid selection")
else:
if f_dict[capitalize]:
capitalize(s)
elif f_dict [title]:
title(s)
elif f_dict[upper]:
upper(s)
elif f_dict [lower]:
lower(s)
elif f_dict[exit]:
print ("Goodbye!! ")
