The difference between a comma and a plus sign in the print function in Python

Let's look at the effect that the comma and the plus sign print separately in print.

Here take Python3 as an example

1	Print ("Hello" + "World")

HelloWorld

1	Print ("Hello", "World")

Hello

World

A plus sign is found here to concatenate strings and commas to concatenate strings with spaces.

Try the actions of different data types:

1	Print ("Hello" + 123)

Typeerror:must is str, not int

1	Print ("Hello", 123)

Hello 123

The plus sign here shows a type error when the str type is added to the NUM type, the comma is concatenated properly and returns the string result.

Summary:

Plus +: The two sides can only be the same data type, in Python is mainly the existence of operators, and strings such as the addition of the type is only a built-in method in Python. Comma,: Here the comma more represents a connection with a space.
