In audio production, the sample rate is the number of samples, or snapshots, per second taken by a digital audio device. Each audio sample contains data that provides the information necessary to accurately reproduce the original analog waveform. This measurement is expressed in hertz or in thousands of Hertz.
The final listing for remember_me.py assumes either that the user has already entered their username or that the program is running for the first time. We should modify it in case the current user is not the person who last used the program.
Before printing a welcome back message in greet_user(), ask the user if this is the correct username. If it’s not, call get_new_username() to get the correct username.
Also, use a check_username() function to prevent any nested if statements from occurring in greet_user()
No prob. Let's go over the Python code,
Here's your complete Python program with the added function `check_username()`:
```
import json
filename = 'username.json'
def get_stored_username():
try:
with open(filename, 'r') as f:
username = json.load(f)
except FileNotFoundError:
return None
else:
return username
def get_new_username():
username = input("What's your username? ")
with open(filename, 'w') as f:
json.dump(username, f)
return username
def check_username():
username = get_stored_username()
if username:
correct = input(f"Are you {username}? (y/n) ")
if correct.lower() == 'y':
return username
return get_new_username()
def greet_user():
username = check_username()
print(f"Welcome back, {username}!")
greet_user()
```
Remember to call `greet_user()` to start the whole shebang. Let me know if anything needs clearing up!
