Lists

# Lists are ordered, changeable and allow for duplicates 

# Define a list 
list1 = ["A", "B", "C", "D", "E", "F"]

# Index a list 
print(list1[0])

# Index nested lists 
print(list1[3][0])

# Change value at index 0 
list1[0] = "X"

# Delete value at index 
del list1[0]

# Insert value at index 
list1.insert(0, "A")

# Append at the end of list 
list1.append("G")

# Find max and min value in list 
print(max(list1))
print(min(list1))

# Reverse list 
list1.reverse()
print(list1)

# Take list back to normal order 
list1 = list[::-1]
print(list1)

# Count how many values in list 
print(list1.count("A"))

# Pop function to remove and return last object 
list1.pop()

# Extend list 
list3 = ["H", "I", "J"]
list1.extend(list3)

# Clear list 
list1.clear()

# Sort list 
list4 = [8, 12, 5, 6, 17, 2]
list4.sort()

# Reverse sort 
list4.sort(reverse=True)

# Copy data to a new list 
list5 = list4.copy()
