For example, you can compare a number and a string for equality with the == operator. However, you’ll get False as a result: Python >>> 2 == "2" False The integer 2 isn’t equal to the string "2". Therefore, you get False as a result. You can also use the != operator...

本章是《流畅的 Python》第二版中的新内容。让我们从重载开始。 重载签名 Python 函数可以接受不同组合的参数。@typing.overload装饰器允许对这些不同组合进行注释。当函数的返回类型取决于两个或更多参数的类型时,这一点尤为重要。 考虑内置函数sum。这是help(sum)的文本: ...
Next, let’s declare a variable and assign a string value to it: date1 = "7/11/2019" And lets declare another variable containing our date mask: datemask = "%m/%d/%Y" Finally, let’s pass our date and mask into the strptime function: ...
The somewhat cryptic output means that the first variable refers to the local first_child() function inside of parent(), while second points to second_child().You can now use first and second as if they’re regular functions, even though you can’t directly access the functions they point...
An example of accessing string.format() variables by index to concatenate strings. Concatenate strings with string.format() (using variable index) name = 'John' surname = 'Smith' result = 'Hi, {1} {0}'.format(name, surname) print(result) # output: Hi, Smith John An example of acces...
