Question

def ask_ok(prompt, retries=4, reminder='Please try again!'):
while True:
ok = input(prompt)
if ok in ('y', 'ye', 'yes'):
return True
if ok in ('n', 'no', 'nop', 'nope'):
return False
retries = retries - 1
if retries < 0:
raise ValueError('invalid user response')
print(reminder)

Answer 1

This code takes input and evaluate whether the user says yes or no. The acceptable values for yes is 'y', 'ye' and 'yes', while acceptable values for no is 'n', 'no', 'nop' and 'nope'. The function by default provides 4 retries. When the retries run out, a ValueError is raised.
