Question

我正在做计算机科学前期论文（NEA），但遇到一个问题，我将数据存储在多维数组中，并询问用户输入，期望的输入已经在数组中了，希望程序打印出存储输入的数组。

# Array containing the ID, last name, year in, membership, nights booked, points.
array = [["San12318", "Sanchez", 2018, "Silver", 1, 2500],
        ["Gat32119", "Gatignol", 2019, "Silver", 3, 7500]]

# Asking to the user to enter the ID
inUser = input("Please enter the user ID: ")

这是我需要帮助的地方，如果输入的ID是“ San12318”，如何获取程序以打印出存储它的阵列？

一个for循环如何检查列表中每个数据记录的第0个索引处的值，即ID值：

def main():
  records = [["San12318", "Sanchez",  2018, "Silver", 1, 2500],
             ["Gat32119", "Gatignol", 2019, "Silver", 3, 7500]]
  input_user_id = input("Please enter a user ID: ")
  print(find_user_id(records, input_user_id.title()))

def find_user_id(records, user_id):
  for record in records:
    if record[0] == user_id:
      return f"Found associated record: {record}"
  return f"Error no record was found for the input user ID: {user_id}"

if __name__ == "__main__":
  main()

示例用法1：

Please enter a user ID: san12318
Found associated record: ['San12318', 'Sanchez', 2018, 'Silver', 1, 2500]

用法示例2：

Please enter a user ID: Gat42119
Error no record was found for the input user ID: Gat42119
