Example Analysis of extended function in python arithmetic operator

Python arithmetic operators in the example analysis of extended functions, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

1. The addition operator supports the ability to concatenate strings.

2. The subtraction operator supports negative operations.

3. The multiplication operator supports adding multiples of a list and n concatenations of strings.

4. Except for the law operator, it must be noted that the denominator cannot be 0, otherwise a syntax error will occur.

Example

Test = 'ACM'tests =' I am ACMER'final = test + tests # where'+ 'concatenates the strings test and tests number = 1000newnumber =-number # here'-'take negative number index = [1Magin2 3] index = index*3print (final) #'+ 'connected test+testsprint (newnumber) print (index) #' * 'multiple added index after reading the above content is helpful to you?
