# Webinar Input Patterns Aug 12 2023

# input() ALWAYS returns a string

# 11 # not a number, but a string if coming from input()!
# 3 96 33 85 # 1 input, that we may want to split... vs the same "numbers" below
# 3 # this is 4 calls to input()
# 96
# 33
# 85

# myInput = input()  # that myInput var is definitely a str!
# but we might want to change it to something else...

# Some common patterns...
# 1 Recast a numeric string into an int or float
# 2 Breaking up a long string into a list of smaller strings
# 3 Break up a string containing numeric chars into a list of
#       recast ints or floats
# 4 One value tells you how many times to call input()
# 5 We DON'T KNOW how many times to call input(), but we know
#       a sentinel value to stop


# 1 Recast a numeric string into an int or float
# 5 looks like a number...  5 but it's really the string "5"
# easy, recast as you call input()
# myInput = int(input()) # float()

# 2 Breaking up a long string into a list of smaller strings
# That's the str split() method!
# "Pat Silly Doe" or "Julia Clark"
# myInput = input()
# strList = myInput.split()
# print(strList)

# 3 Break up a string containing numeric chars into a list of
#       recast ints or floats
# This combines the first 2 patterns above, and involves a for loop.
# 12 44 67 23
# myInput = input()
# strList = myInput.split()
# # myInput = input().split()
# print(strList)
# numList = []
# for num in strList:
#     numList.append(int(num))
# print(numList)

# 4 One value tells you HOW MANY TIMES to call input()
# Any "known number of times" means a for loop
# 5
# 30.0
# 50.0
# 10.0
# 100.0
# 65.0

# call input() to get the number of times
# numVals = int(input())
# # for loop over range()
#
# floatList = []
# for num in range(numVals): # do this thing, this many times
#     nextInput = float(input())
#     floatList.append(nextInput)
# print(floatList)


# 5 We DON'T KNOW how many times to call input(), but we know to stop on some SENTINEL VALUE
# this is a WHILE loop condition

# ask for the FIRST input()
# myInput = input()
# # then set up a WHILE LOOP
# while myInput != "quit": # while myInput != "-1"
#     # do what you need with that input...
#
#     # get the next input()
#     myInput = input() # get the next input for the next iteration of the loop

# A variation on this: Multiple quit commands
# quit, done, d
myInput = input()
quitCommands = ["quit", "done", "d"]
while not myInput in quitCommands:
    # do your stuff
    print(f"I got the command: {myInput}")
    myInput = input() # again, get the next input
print("OK. Done!")
