如何列出参加python比赛的参赛者的姓名、时间和位置?

基本上,我需要为4个组创建一个参与者列表(我想对这些组进行排序),记录他们在比赛中的时间和排名,并生成一个格式整洁的结果表。

racers = [(i, l[i]) for i in l]

places = sorted(racers, key = lambda i: int(i[1]))

print('1st Place: {}'.format(places[0][0]))
print('2nd Place: {}'.format(places[1][0]))
print('3rd Place: {}'.format(places[2][0]))

这是我当前的代码:

l = []
a = int(input("Enter the amount of racers for Anstey: "))
g = int(input("Enter the amount of racers for Gordon: "))
h = int(input("Enter the amount of racers for Helps: "))
r = int(input("Enter the amount of racers for Rawle: "))
total_racers = a+g+h+r

print("Total Racers:",total_racers)

for i in range(total_racers):
  racer_name = (input("Participant Name: "))
  racer_time = int(input("Participant Time: "))
  time_name = racer_time,racer_name
  l.append(time_name)

print('\n',*l, sep='\n')

在这里。

import xlsxwriter

# XLSXWRITER uses O as first row or column
row = 1 # 2nd row... leave room for Headers
col = 0 # 1st column

# Assign Names and Registration Numbers to Contestants
while True:
    print("\nEnter q to stop entering names", "\n")
    while True:
        fname = input("Enter First Name: ")
        if fname.isalpha():
            break
        else:
            print("Please ONLY use letters A-Z")
            continue
    if str(fname) == 'q':
            break

    while True:
        lname = input("Enter Last Name: ")
        if lname.isalpha():
            break
        else:
            print("Please ONLY use letters A-Z")
            continue

    while True:
        house = input("Enter House: ")
        if house.isalpha():
            break
        else:
            print("Please ONLY use letters A-Z")
            continue


    dob = input("Enter Date of Birth 'dd/mm/yyyy': ")

    while True:
        try:
            regno = int(input("Enter Registration Number: "))
        except ValueError:
            print(" That is not a valid number")
            continue
        else:
            break

    print("\n")
    date = workbook.add_format({'num_format': 'dd/mm/yyyy'})
    worksheet.write(row, col, fname) # First Name
    worksheet.write(row, col+1, lname) # Last Name
    worksheet.write(row, col+2, house) # House
    worksheet.write(row, col+3, dob) # Date of Birth
    worksheet.write(row, col+4, regno, date) # Reg. No. # 28/02/13
    row = row+1

l 已经是一个列表,不需要创建另一个列表 racers 用于排序。如果需要,可以指定 racers = l

time_name (racer_time, racer_name) ,和 key 排序应该是 i[0] ,这是 racer_time ,您现在正在使用 i[1] racer_name )排序

racers = l
sorted(l, key = lambda i: i[0])

或者你应该换个位置和 赛车手姓名 ,例如。 time_name = racer_name,racer_time ,因为我想你会想打印最后,但是 places[0][0] 实际上是 比赛时间
