use. timeit In the same spirit as the experimentation in the Python interpreter, the module timeit provides functions to timesmallcode fragments. timeit.timeit() in particular can be called directly, passing some Python code in a string. Here’s an example: Python >>> from timeit import...
# print(a) # a = 10 # 注意:函数必须先定义,后使用 # print(get_water) def get_water(water, money): print('收入你的%d元钱' % money) print('给你%s水种' % water) return water # 使用函数:# 1.根据需求定义函数# 2.通过函数名找到函数所在的位置(内存地址)# 3.函数名() 执行函数地址...
Finally, if you don’t want to use the ROUND() function, you can use a few alternatives. The CEIL() and FLOOR() functions both take a single number as an input and return the nearest integer. The TRUNC() function takes a single number as an input and returns the integer part of th...
Functional Programming in Python: When and How to Use It In this quiz, you'll test your understanding of functional programming in Python. You'll revisit concepts such as functions being first-class citizens in Python, the use of the lambda keyword, and the implementation of functional code ...
Assigning functions to variables To kick us off we create a function that will add one to a number whenever it is called. We'll then assign the function to a variable and use this variable to call the function. def plus_one(number): return number + 1 add_one = plus_one add_one(5...
