As it turns out, we can use the ternary operator in Python that allows us to compress anifstatement into a single line. Check out this tutorial on our blog if you want to learn more about the exciting ternary operator in Python. Theternary operatoris very intuitive: just read it from le...
Overall, I am quite surprised by the kinds of games I could manage. My daughter and I had lots of fun playing and tweaking some of these games. They are probably the most fun I could get from one line of code.
One line if else statement: a =2 b =330 print("A")ifa > belseprint("B") Try it Yourself » This technique is known asTernary Operators, orConditional Expressions. You can also have multiple else statements on the same line:
one_line = 'yes' if predicate(value) else 'no'slightly_split = ('yes' if predicate(value) else 'no, nein, nyet')the_longest_ternary_style_that_can_be_done = ( 'yes, true, affirmative, confirmed, correct' if predicate(value) else 'no, false, negative, nay') No: bad_line_bre...
This is a good use of the ternary operator because the condition is simple and only one decision needs to be made. 4.2 Avoid Verbosity Avoid using the ternary operator to perform multiple actions or to handle complex conditions, as this can make the code more difficult to read and understand...

:' ternary operator "yahoo!" if 3 > 2 else 2 # => "yahoo!" 上段代码等价于: if 3 > 2: return 'yahoo' else: return 2 list Python中用[]表示空的list,我们也可以直接在其中填充元素进行初始化: # Lists store sequences li = []

Ternary运算符是用于显示条件语句的运算符。这包含true或false值,并且必须为其评估语句。 三元运算符将被给出为: [on_true] if [expression] else [on_false] x,y = 25,50big =x if x <y else y 表达式的计算方式与x <y else y一样,在这种情况下,如果x <y为真,则返回值为big = x,如果不正确则...
