python list append documentation code example
Example 1: Python dictionary append
# to add key-value pairs to a dictionary:
d1 = {
"1" : 1,
"2" : 2,
"3" : 3
} # Define the dictionary
d1["4"] = 4 # Add key-value pair "4" is key and 4 is value
print(d1) # will return updated dictionary
Example 2: python list append
# Python list mutation, adding elements
history = ["when"]
# adds item to the end of a list
history.append("how")
# ["when", "how"]
# combine lists
history.extend( ["what", "why"] ) # works with tuples too
# or
history = history + ["what", "why"]
# ["when", "how", "what", "why"]
# insert at target position
history.insert(3, "where")
# ["when", "how, "what", "where", "why"]
