   • and
   • or
   • not
   • != (not equal)
   • == (equal)
   • >= (greater-than-equal)
   • <= (less-than-equal)

# _*_ coding:utf-8 _*_print (True and False), Falseprint (False and True), Falseprint (1 == 1 and 2 == 1), Falseprint ("test" == "test"), Trueprint (1 == 1 or 2 != 1), Trueprint (True and 1 == 1), Trueprint (False and 0 != 0), Falseprint (True or 1 == 1), Trueprint ("test" == "testing"), Falseprint (1 != 0 and 2 == 1), Falseprint ("test" != "testing"), Trueprint ("test" == 1), Falseprint not (True and False), Trueprint not (1 == 1 and 0 != 1), Falseprint not (10 == 1 or 1000 == 1000), Falseprint not (1 != 10 or 3 == 4), Falseprint not ("testing" == "testing" and "Zed" == "Cool Guy"), Trueprint not (1 == 1 and not ("testing" == 1 or 1 == 0)), Falseprint not ("chunky" == "bacon" and not (3 == 4 or 3 == 3)), Trueprint (3 == 3 and not ("testing" == "testing" or "Python" == "Fun")), Falseprint "test" and "test" #輸出test，布爾操作符and和or會輸出操作符兩側的內容，而不是True和Falseprint "test" or "test"print not ("test" and "test")

注意"test" and "test" = "test"，而不是1。or也是如此
