# # 2024 July 6
# # WEBINAR: For Loops
#
# # We use loops to repeat actions
# a WHILE loop... is an IF that repeats as long as the loop condition remains True

# FOR LOOPS are used for repeating actions for every element in a container (list, dict, tuple, str)

# Basic syntax of a for loop
# for ___ in _someContainer_:

# # LIST
myList = ["Agent Scully", "Agent Mulder", "Walter Skinner", "CSM", "Mr. X"]
# for item in myList:
#     print(item)
#
# # TUPLE
# myTuple = ("Gilligan", "Castaway002", "red", "crew")
# for item in myTuple:
#     print(item)
#
# # STRING
# myString = "It was the best of times."
# for char in myString:
#     print(char)

# DICT
# myDict = {
#     key: value,
#     key: value,
#     key: value
# }
# myDict[key] # get the value for that key
# myDict[key] = value # assigns value to that key

bestOfXF = {
    "1x00": "Pilot",
    "2x10": "Red Museum",
    "2x14": "Die Hand Die Verletzt",
    "3x04": "Clyde Bruckman's Final Repose",
    "3x12": "War of the Coprophages",
    "3x20": "Jose Chung's From Outer Space",
    "4x05": "The Field Where I Died",
    "5x05": "The Post Modern Prometheus",
    "5x17": "All Souls"
}
for key in bestOfXF: # loop var holds the KEY
    # value = bestOfXF[key]
    # "Check out Episode ___ or '---'."
    print(f"Check out Episode {key} of '{bestOfXF[key]}'.")

# Loop a known of number of times
# RANGE
# range(start=0, stop, step=1)
# range(5) # range(0, 5), range(0, 5, 1) --> [0, 1, 2, 3, 4]
# for n in range(5):
#     print(n)

# Looping over a container and I need to know the index
# 2 ways to do that
# use a range() with len()
for i in range(0, len(myList), 1):
    print(f"{i}: {myList[i]}")

# or... enumerate()
for i, item in enumerate(myList):
    print(f"{i} --> {item}")
