In this tutorial, you'll prepare for future interviews by working through a set of Python practice problems that commonly appear in coding tests. You'll work through the problems yourself and then compare your results with solutions developed by the Real
print(",".join(r)) # join的sequence只能是str类型的 # Question13: # 输入一个句子,统计字母的个数、数字的个数 def Q13(): time_map={"DIGITS":0,"LETTERS":0} s=input() for i in s: if i.isalpha(): time_map["LETTERS"]+=1 elif i.isdigit(): time_map["DIGITS"]+=1 else: cont...
Question 15: Complete the code to define a recursive function gcd that calculates the greatest common divisor (GCD) of two numbers using the Euclidean algorithm. def gcd(a, b): if b == 0: return a return gcd(b, ___) ▼ Question 16: What will be the output of the following code?
# Question 26: # 计算两数之和 def Q26(n1,n2): return(n1+n2) # Question 27: # int转str,并输出 def Q27(n): s=str(n) print(s) # Question 29: # 输入两个str类型的整数,计算和 def Q28(): num=input("two number: ").split(",") ...
An interesting interview question might be to ask you to refactor these two solutions to find a way to share code and make them more maintainable. Problem Description This problem is a little different from the previous two. For this section, take your solutions from the previous problems and ...
In this project, you will have to create a question bank with multiple choices for each question and then implement a scoring system for the players who attempt the quiz. Try to store each unique player’s score using a file or a database at the end of each quiz attempt. 16. Calculator...
Or we could be asked this as a following question, since they both give the same result.We could use the dis module to see what's going on:2 0 LOAD_CONST 0 (<code object a at 0x0000029C4D3C2DB0, file "<dis>", line 2>) 2 LOAD_CONST 1 ('a') 4 MAKE_FUNCTION 0 6 STORE_...
