缩短Python if-statement语法是通过使用三元表达式和逻辑运算符来实现的。在传统的if-else语句中,可以使用条件判断来执行不同的代码块。而通过使用三元表达式,可以在一行代码中实现相同的功能,从而减少了代码量并提高了可读性。 三元表达式的语法如下: 代码语言:txt ...
main__": print("ONE.py is being run directly") # line 1.3 else: print(f"ONE.py...
python python-3.x function if-statement 为什么下面的代码只产生True?输出不应该是这样的吗: True False 因为没有其他说法。因此,一旦它验证并执行了if命令,它是否也应该读取该命令。因为此命令不在“If”缩进中,甚至没有与else一起提及。 def is_even(number): if number % 2 == 0: return True return ...
