# # 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)
#
# # STR
# 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:
#     # "Check out Episode ___ or '___'"
#     print(f"Check out Episode {key} or '{bestOfXF[key]}'.")

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

# if we're interested in the INDEX, we can loop over the RANGE of the LENGTH
for i in range(0, len(myList), 1):
    print(f"{i}: {myList[i]}")

# another way to loop focused on the INDEX is using ENUMERATE
# for i, item in enumerate(myList):
#     print(f"{i}--> {item}")
