String Concatenation

Concatenation means joining strings together to make one string.

Example

first = "Ada"
last = "Lovelace"
full = first + " " + last
print(full)
# outputs: Ada Lovelace

Rules

• Use + to join strings.
• Add spaces yourself: "Hello" + " " + "world".
• Convert non-strings with str() or use f-strings.

More Examples

Print a message with a count:

When concatenating a string with a number, you need to convert the number to a string using the str() function. If you don't, you will get a type error.

count = 3
print("You have " + str(count) + " new messages")

Print a dynamic border with end and beginning characters:

border_width = 10
# subtract 2 for the "-" characters to account for the beginning and ending "+" characters os that they still add up to the border_width
print("+" * "-" * (border_width - 2) + "+")
# outputs: +----------+
