This article mainly introduces "how to write python summation code". In daily operation, I believe many people have doubts about how to write python summation and code. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "python summation and code writing". Next, please follow the editor to study!

1. Use for loop to define a cumulative summation function sum2 (n). The function of for loop is loop traversal.

Def Sum (* args): count = 0 for i in args: count+=ireturn count

2, the use of recursive function, define a cumulative summation function sum3 (n), recursive function must be set recursive exit, that is, when the function meets a condition, the function is no longer executed, in order to prevent an endless loop; set when nail1, we let the function return 1DING return the code is not executed.

Def sum_numbers (num): # 1. Export if num = = 1: return 1 # 2. Array accumulation temp = sum_numbers (num-1) return num + temp result = sum_numbers (3) print (result) so far, the study on "how to write python summation code" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
