python print statement

Python print statement

The print statement can output the specified text to the screen. For example, output ‘hello, world’, using code to achieve the following:

>>> print 'hello, world'

note:

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

2. When we write code in a text editor, do n’t add >>> yourself .

The print statement can also be followed by multiple strings, separated by a comma “,” to join a series of output:

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

Print prints each string in turn, and a comma “,” will output a space, so the output string is spelled like this:

Print can also print integers, or calculate the result:

>>> print 300
300 #Run result
>>> print 100 + 200
300     #Run result

Therefore, we can print the result of computing 100 + 200 more beautifully:

>>> print '100 + 200 =', 100 + 200
100 + 200 = 300      #Run results

Note: For 100 + 200, the Python interpreter automatically calculates the result 300, but ‘100 + 200 = ‘ is a string rather than a mathematical formula, and Python treats it as a string. Please explain the above print results yourself.
