Python's print statement

The print statement can output the specified text to the screen. For example, the output of ' Hello, world ', implemented in code as follows:

>>> print ' Hello, world '

Attention:

1. When we write code in a python interactive environment, >>> It is a prompt for the Python interpreter, not part of the code.

2. When we write code in a text editor, never add >>> yourself.

The print statement can also be followed by multiple strings, separated by a comma "," that can be connected to a string of outputs:

>>> print ' The quick brown fox ', ' Jumps over ', ' The lazy dog ' The quick brown fox jumps over the the lazy dog

Print prints each string sequentially, encounters a comma "," and outputs a space, so the output string is spelled like this:

Print also prints integers, or calculates the result:

>>> print 300300    #运行结果 >>> print + 200300    #运行结果

Therefore, we can print the results of the calculation 100 + 200 more beautifully:

>>> print ' + + = ', + 200100 + +-     #运行结果

Note: For the + 200,python interpreter automatically calculates the result 300, but, ' 100 + 200 = ' is a string rather than a mathematical formula, Python treats it as a string, please explain the above printing results yourself.
