Am I Making Progress in Learning Python?

I've just started learning Python and wanted to share my code from the first few days to see if I'm on the right path. Here's what I've got so far:

On my first day, I wrote a simple calculator function that takes two numbers as input and prints their sum:
```python
def calc():
first = float(input("nEnter first number: "))
second = float(input("Enter second number: "))
result = first + second
print(f"nOkay people, now your count is {result}")

def main():
print("Hello, Man")
calc()

if __name__ == "__main__":
main()
```

On my third day, I shifted gears and wrote a checklist program that handles adding, deleting, and displaying items:
```python
#!/usr/bin/python3
from os import system, name

buffer = "--NONE--"

def clear():
system('cls' if name == 'nt' else 'clear')

def Add():
global buffer
if buffer == "--NONE--":
buffer = input("Your case: ")
else:
buffer += "n"
buffer += input("Your case: ")
print("ADDED")
clear()
Do()

def Delete():
global buffer
buffer = "--NONE--"
print("DELETED")
clear()
Do()

def Exit():
clear()
exit()

def __init__():
print(f"n{buffer}")

def Display():
print("||==============================================||")
print("||===============CheckList-0.1v=================||")
print("||==============================================||")
__init__()
Do()

def Do():
print("n[1] - Add [2] - Delete [3] - Display [4] - Exit")
do = int(input("What you do? "))
if do == 1:
Add()
elif do == 2:
Delete()
elif do == 3:
Display()
elif do == 4:
Exit()
else:
print("What?")
Do()

def main():
Display()

if __name__ == "__main__":
main()
```

I'd love to hear any feedback about my work so far!
