complete python bootcamp review

Remember, in the previous section, we introduced the if statement specifically: the process of starting the if statement. When learning the if statement, I do not know much about the basic knowledge of python Programming. maybe I have not done anything that is too complicated. This article will review it and improve the basic statement structure through review.

Review the if statement in Python and learn pythonif Basic statement Structure Copy codeThe Code is as follows:If condition 1:Execute Statement 1 ......Elif judgment condition 2:Execute Statement 2 ......Elif judgment Condition 3:Execute Statement 3 ......Else:Execute Statement 4 ...... The following execution statement is executed only when the value of "judgment condition" is True. In

first, but doing nothing) In exception handling, it is possible to pass directly to an exception that has little impact 10. Again the Else statementIn Python, in addition to using else in a conditional statement, you can also use the Else statement in the while and for loops. When used in a loop, the ELSE clause executes only after the loop completes, that is, if a break statement exists in the loop, the Else statement is skipped.For

I was a minor in mathematics during my undergraduate course, but I definitely need to review this knowledge. These quick look tables provide the math behind most of t
