Webinar Input Patterns

# Webinar Input Patterns

# input() ALWAYS returns a string

# 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
# myVar = int(input()) # float(input())
# print(type(myVar).__name__)

# 2 Breaking up a long string into a list of smaller strings
# "Pat Silly Doe" or "Julia Clark"
# myVar = input()
# strList = myVar.split()
# print(strList)

# 3 Break up a string containing numeric chars into a list of
#       recast ints or floats
# 22 88 32 68
# myVar = input()
# strList = myVar.split()
# print(strList)

# fill the basket
# numList = []
# for num in strList:
#     # recast = int(num)
#     # numList.append(recast)
#     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
# numTimes = int(input())
#
# # set up a for loop to get the next inputs
# # and fill a basket if needed
#
# floatList = []
# for num in range(numTimes): # [0, 1, 2, 3, 4]
#     # get the input
#     # nextInput = float(input())
#     # floatList.append(nextInput)
#     floatList.append(float(input()))
# 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

# get the first input()
myVar = input()

# set up a while loop to see if we should continue after this
# while myVar != "quit": # whatever the sentinel value to stop is
while myVar != "-1":
    # do your stuff

    # x += 1
    myVar = input()

# What if we had multiple sentinel values
myVar = input()
# create a list of the sentinel values
quitCommands = ["quit", "done", "d"]

# while loop
while not myVar in quitCommands:
    # do your stuff

    myInput = input()

# To recap our 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

# You'll use variations on these a lot!
