Webinar Input Patterns Sept 2024

# Webinar Input Patterns Sept 14

# 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
# myInput = input()
# print(type(myInput).__name__)
# myInput = int(input())
# print(type(myInput).__name__)

# 2 Breaking up a long string into a list of smaller strings
# "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
# 22 88 32 68
# strList = input().split()
# print(strList)
#
# # fill the basket
# numList = []
# for num in strList:
    # recast = int(num)
    # numList.append(recast)
    # or
    # 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())
#
# # fill the basket
# floatList = []
# for n in range(0, numTimes):
#     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

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

# set up a while loop using that var in its condition
# while myInput != "quit":
# while myInput != "-1": # while myInput != -1:
#     # do the stuff you need with that piece of data
#
#     myInput = input() # the next for next iteration
#


# Variation on this pattern: multiple sentinel values!
# Use a list for multiple sentinel values
# Stop on quit, done, or d

# myInput = input()
# quitCommands = ["quit", "done", "d"]
#
# while not myInput in quitCommands:
#     # do stuff
#     myInput = input()
