foo=long_function_name(var_one,var_two,var_three,var_four) 当if语句的条件部分足够长,需要跨多行编写时,值得注意的是,两个字符的关键字(即 if),加上一个空格,再加上一个开括号,会为多行条件的后续行创建一个自然的4个空格缩进。这可能会在if语句内嵌的缩进代码块的可视上产生冲突,后者也会自然地缩进...
We can use Python not equal operator withf-stringstoo if you are using Python 3.6 or higher version. x = 10 y = 10 z = 20 print(f'x is not equal to y = {x!=y}') flag = x != z print(f'x is not equal to z = {flag}') # python is strongly typed language s = '10'...
align:可选参数,用于指定对齐方式(值为“<”是表示内容左对齐;值为“>”时表示内容右对齐;值为“=”时表示内容右对齐,将符合放在填充内容的最左侧,且值对数字类型有效;值为“^”时表示内容居中),需要配合width一起。 sign:可选参数,用于指定有无符号数(值为“+”表示正数加正号,负数加负号;值为“-”表示正...
或 is not None 而不是 == None 或 != None。因为None在Python里是个单例对象,一个变量如果是None,它一定和None对象指向同一个内存地址。is运算两个对象在内存中的地址是否一致,而 == 运算符是比较对象的值是否相等。 使用= None 或 != None会警告:Comparison with None performed with equality operators...

Testing boils down to comparing an observed value with an expected one to check if they’re equal or not. This kind of check perfectly fits into assertions. Assertions must check for conditions that should typically be true, unless you have a bug in your code. This idea is another ...

由于numpy是python中的一个库,所以逻辑运算不能直接使用python 中的and、or、not了 要换成logical_or、logical_and、logical_not a = np.array([True, False]) b = np.array([False, True]) res = np.logical_or(a, b) print('logical_or的结果', res) ...
