Question

我正在尝试将多个数字添加到多个列表中。

我想按顺序输入：患者一：变量一，变量二，变量三患者二：变量一，变量二，变量三患者三：变量一，变量二，变量三

我想出了如何以错误的顺序从词典中获取信息。

但当前输入顺序为：患者一：变量一，患者二：变量一，患者三：变量一患者一：变量二，患者二：变量二，患者三：变量二患者一：变量三，患者二：变量三，患者三：变量三

有什么建议吗？

while True:
        print("")
        number_of_persons=(input("Please enter no. of persons \n"
         "Whole digit only. \n"
   "Positive Number:"))

        if number_of_persons.isdigit():
            print("Thanks")
            break
        try:
            pass
        except:
            pass

number_of_persons=int(number_of_persons)

variable_one = []
variable_two = []
variable_three = []

for person in range(0,number_of_persons):
    while True:
        print("Person Number: " ,person + 1)
        a=(input("     Enter variable one: "))

        if a.isdigit():
            print("Thanks")
            variable_one.append(a)
            break
        try:
            pass
        except:
            pass


for person in range(0,number_of_persons):
    while True:
        print("Person Number: " ,person + 1)
        b=(input("     Enter variable two: "))

        if b.isdigit():
            print("Thanks")
            variable_two.append(b)
            break
        try:
            pass
        except:
            pass


for person in range(0,number_of_persons):
    while True:
        print("Person Number: " ,person + 1)
        c=(input("     Enter variable Three: "))

        if c.isdigit():
            print("Thanks")
            variable_three.append(c)
            break
        try:
            pass
        except:
            pass        


print(variable_one)
print(variable_two)
print(variable_three)

Answer 1

首先，您要处理的是列表，而不是 dictionaries 。这是拥有列表列表的一种方法：

while True:
        print("")
        number_of_persons=(input("Please enter no. of persons \n"
         "Whole digit only. \n"
   "Positive Number: "))

        if number_of_persons.isdigit():
            print("Thanks")
            break

number_of_persons=int(number_of_persons)

variables = []
for i in range(number_of_persons):
    variables.append([]) # a list of lists

for person in range(number_of_persons):
    for n in range(3):
        while True:
            a = input(f"Person Number: {person + 1}, variable {n + 1}: ")
            if a.isdigit():
                print("Thanks")
                variables[person].append(a)
                break

print(variables)

Answer 2

这是使用字典的一种方式。

def input_number(i):
    while True:
        try:
            number = int(input(f"\tEnter variable {i+1}: "))
            print("\n")
            break
        except ValueError:
            print("Only integers accepted!\n")
    return number


while True:
    try:
        print("Please enter no. of persons")
        print("Whole digit only.")
        number_of_persons = int(input("Positive number: "))
        break
    except ValueError:
        print("Only integers accepted!\n")


variables = {}
for person in range(number_of_persons):
    print("----------------------------------------")
    vars_ = []
    for i in range(number_of_persons):
        print(f"Person Number: {person + 1}")
        a = input_number(i)
        vars_.append(a)
    variables[person+1] = vars_


print("\n")
print(variables)
for j in range(len(variables)):
    print(variables[j+1])

示例输出：

Please enter no. of persons
Whole digit only.
Positive number: 2
----------------------------------------
Person Number: 1
    Enter variable 1: 50


Person Number: 1
    Enter variable 2: 100


----------------------------------------
Person Number: 2
    Enter variable 1: 150


Person Number: 2
    Enter variable 2: 200




{1: [50, 100], 2: [150, 200]}
[50, 100]
[150, 200]
