10. Logical expressions

• We can combine logical operators to form complex logical expressions

• The evaluation order is: not > and > or. This means that in an expression, the not logical operator is evaluated first, then and, and finally or.

Let’s see an example:

1 print(not False or False and True) 2 print(False or True and True) 3 print(not False and True or False) Edit this code line that just executed next line to execute << First < Prev Next > Last >> Step 1 of 3 Submit Python Tutor by Philip Guo Customize visualization (NEW!)

10.1. Example

• The conditions for granting a motorcycle purchase loan are: having a salary greater than $1,000.00 and being over 18 years old. Check if José can get the loan:

1 salary = 500.0 2 age = 20 3 print(salary > 1000 and age > 18) Edit this code line that just executed next line to execute << First < Prev Next > Last >> Step 1 of 3 Submit Python Tutor by Philip Guo Customize visualization (NEW!)

10.2. Example

• Check if a student passed given that they obtained an average score of 5.8 in the exercise program and obtained an average score of 7 in the tests:

1 ep = 5.8 2 p = 7 3 passed = ep >= 6 and p >= 6 4 print(passed) Edit this code line that just executed next line to execute << First < Prev Next > Last >> Step 1 of 4 Submit Python Tutor by Philip Guo Customize visualization (NEW!)
