String Concatenation in Python

Remember that string concatenation is used to dynamically generate messages that can be different depending on context.

We most often use it with variables, let's check an example:

adjective = "awesome"
message = "AlgoCademy is "

# String concatenation & assignment:
message = message + adjective

print(message) # Output: AlgoCademy is awesome

We first concatenate message and favoriteAnimal and then we assign the result to message.

Concatenating with +=

Since this is such a common pattern, there is the += operator which does both the concatenation and assignment in one step.

adjective = "awesome"
message = "AlgoCademy is "

# With += operator:
message += adjective

print(message) # Output: AlgoCademy is awesome

Concatenating multiple strings:

We can append as many strings as we want using the += operator:

name = "Andy"
pet = "dog"
message = "Hey, "

message += name
message += "! Nice ";
message += pet
message += "!" 

print(message) # Output: Hey, Andy! Nice dog!
