# in their account realize necessary operation on users balance

# and print a message if task is completed or failed. Such as;

# e.g.

# You withdraw: 10

# Your balance: 20

# or

# Insufficient funds...

# Deposit: Ask user amount to deposit like "Please put deposit amount in..." and

# check entered amount for any possible invalid inputs that may cause malfunction of

# your program. (e.g. negative inputs) then realize requested action on balance.

# Balance: Print balance on the screen

I couldn't figure out how to implement menu = 0 and maybe there are some bugs in my code,indentations doesn't properly copied in here.Goal is to write this without any function and with if-else statements(Python)
