DICTIONARY 1. Repeatedly ask the user to enter a team name and how many games the team has won and how many they lost. Store this information in a dictionary where the keys are the team names and the values are the lists of the form [wins, losses]. (a) Using the dictionary created above, allow the user to enter a team name and print out the teams winning percentage. (b) Using the dictionary, create a list whose entries are the number of wins of each team. (c) Using the dictionary, create a list of all those teams that have winning records. team_dict ={} winningList=[] winningTeam=[] numofTeams=int(input("Insert Number of Teams: ")) for x in range(numofTeams): teamName=input('Team Name: ') winLossList=[] wins = int(input('Wins: ')) winningList.append(wins) losses=int(input('Losses: ')) if(wins>losses): winningTeam.append(teamName) winLossList.append(wins) winLossList.append(losses) team_dict[teamName] = winLossList print(...

TUPLE 1. Write a Python program that creates a tuple storing first 9 terms of Fibonacci series. fib=(0,) n=int(input('Please enter a number ')) a,b=0,1 for i in range(n): a, b = b, a+b fib=fib+(a,) print(fib) 2. (a) Write a program that receives the index and returns the corresponding value. fib=(0,) n=int(input('Please enter a number ')) a,b=0,1 for i in range(n): a, b = b, a+b fib=fib+(a,) print(fib) readInput=int(input("Enter an index ")) print("Element at index ",readInput," is : ",fib[readInput]) (b) Write a program that receives a Fibonacci term and returns a number telling which term it is for instance, if you pass 3, it returns 5, telling it is 5th term; for 8, it returns 7. fib=(0,) n=int(input('Please enter a number ')) a,b=0,1 for i in range(n): a, b = b, a+b fib=fib+(a,) print(fib) readInput=int(input("Enter a fibonacci term: ")) print(fib.index(readInput)+1) 3.
