Python Basic Tutorial Operations

Python operators are similar to other languages

(We only know the basic usage of these operators for the time being, so we could expand the content later, the advanced application is not introduced at the moment)

Mathematical operations

>>>print 1+9        # addition >>>print 1.3-4      # subtraction >>>print 3*5        # multiplication >>>print 4.5/1.5    # Division >>>print 3**2       # exponentiation     >>>print 10%3       # seek remainder

Judge

Judging whether it's true or false, return to True/false

>>>print 5==6               # =, equal to >>>print 8.0!=8.0           #! =, unequal >>>print 3<3, 3<=3          # < Less than <=, less than or equal to >>>print 4>5, 4>=0          #, greater than >=, greater than or equal to >>>print 5 in [1,3,5]       # 5 is list [1,3,5 ] an element of

(also is, are not, etc., temporarily not in depth)

Logical operations

Operations between the True/false

>>>print true and True, True and False      # and, and, both are true >>>print true or False                      # or, "or" operation, One of which is true is true >>>print not true                           # not, "non" operation, negation

You can do some exercises with the previous section, such as:

>>>print 5==6 or 3>=3
