Python | Lesson3 | Map

 

# Declaring a map (dictionary)

Employee = {"name": "David", "age": 25, "profession": "Engineer"}

# Accessing elements in a map

print(Employee["name"])

# Output: "David"

print(Employee["age"])

# Output: 25

# Modifying elements in a map

Employee["age"] = 25

print(Employee) # Output: {"name": "David", "age": 25, "profession": "Engineer"}

# Adding elements to a map

Employee["location"] = "New York"

print(Employee) # Output: {"name": "David", "age": 25, "profession": "Engineer",

# "location": "New York"}

# Removing elements from a map

del Employee["location"]

print(Employee) # Output: {"name": "David", "age": 25, "profession": "Engineer"}

# Finding the length of a map

print(len(Employee))

# Output: 3

# Iterating through a map

for mapKey in Employee:

    print(mapKey, Employee[mapKey])

# Output:

# name David

# age 25

# profession Engineer
