# Webinar Input Patterns
# Sept 10, 2022

# input() ALWAYS returns a string
# myInput = input()
#
# but we might want to change it to something else...

# 1 Turn 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 Turn a numeric string into an int or float
# myInput = input()
# myInput = "5"
# myInput = int(input()) # float(input())

# 2 Breaking up a long string into a list of smaller strings
# myInput = "Pat Silly Doe" # input()
# strList = myInput.split() # str split() turns a long str into a list of short str
# print(strList)

# 3 Break up a string containing numeric chars into a list of
#       recast ints or floats
# # Lab 28.11... 10 5 3 21 2
# myInput = "31 567 2 93 6" # input()
# strList = myInput.split()
# print(strList)
# numList = []
# for num in strList:
#     numList.append(int(num))
# print(numList)

# you could do this with a LIST COMPREHENSION
# [expression for item in other container]
# myInput = "2 34 87 234 99" # input().split()
# strList = myInput.split()
# numList = [int(num) for num in strList]
# print(numList)

# 4 One value tells you how many times to call input()
# for example 6.17
# example inputs for 6.17:
# 5
# 30.0
# 50.0
# 10.0
# 100.0
# 65.0

# numValues = 5 "# int(input())
# floatValues = []
# for n in range(0, numValues): # first input
#     nextInput = float(input())
#     floatValues.append(nextInput)
#
# # to finish out that Lab...
# theMax = max(floatValues)
# for num in floatValues:
#     print("{:.2f}".format(num/theMax))

# 5 We DON'T KNOW how many times to call input(), but we know
#       a sentinel value to stop

# ask for the FIRST input()
myInput = input()
# THEN we can loop...
while myInput != "-1":
    # do our stuff

    myInput = input() # last thing... get the next input()

# multiple quit commands
# Done, done, d
myInput = input().strip() # I haven't been stripping inputs, but it's always a good idea!
# while myInput != "Done" and myInput != "done" and myInput != "d":
quitCommands = ["Done", "done", "d"]
while myInput not in quitCommands:
    # do your stuff

    myInput = input().strip()
