虽然循环没有输出正确的数据

Question

所以我按照大家的建议对我的代码进行了更正。我能够进入循环，但是一旦我输入了正确的名称，我仍然无法摆脱它。有什么建议？ 这是我得到的：

import csv

full_name = input('Enter your full name: ').lower()

with open('Report1.csv') as csvfile:
    hour_summation = {}
    read_csv = csv.reader(csvfile, delimiter=',')
    for row in read_csv:
        while (' '.join((row[0], row[1]))).lower() != full_name.strip().lower():
            print('Name is not in system')
            full_name = input('Enter your full name: ').lower()
        if(' '.join((row[0], row[1]))).lower() == full_name.strip().lower():
            hour_summation[row[2]] = hour_summation.get(row[2], 0) + int(float(row[3]))
print('This is {} full hours report:'.format(full_name))
for k, v in hour_summation.items():
    print(k + ': ' + str(v) + ' hours')

这是我输入时的结果： 供参考。 Steve Miller 不在 csv 文件中，因此第一个响应是正确的。但是，Sri Mantri 在文件中，它应该继续打印出她名下的所有列表。

Enter your full name: Steve Miller
Name is not in system
Enter your full name: Sri Mantri
Name is not in system

这是代码运行时的输出结果。

Enter your full name: Sri mantri

Answer 1

如果您真的对其他解决方案感兴趣，请选择我的答案，否则请跳过它。使用 pandas 可以更轻松地解决您的需求。

所以我有一个包含这些值的 CSV 文件（“names.csv”），

Name    Hours
Sri Mati    1
Some Name   2

代码如下：

import pandas

if __name__ == "__main__":
    csv = pandas.read_csv("names.csv")
    name = input("Enter your name: ")
    if (csv["Name"]==name).any():
        print("Name Present")
        correct_name = csv.loc[csv["Name"] == name]
        # print everything
        print(csv)
        print()
        #print correct name
        print(correct_name)
        print() # for clear display
        # get individual things
        print("Correct Inidividual Values")
        print(correct_name.values)
    else:
        print("Name not there")

示例输入和输出：

Enter your name: Steve Miller
Name not there

下一次运行，

Enter your name: Sri Mati
Name Present
        Name  Hours
0   Sri Mati      1
1  Some Name      2

       Name  Hours
0  Sri Mati      1

Correct Inidividual Values
[['Sri Mati' 1]]

Answer 2

您的 while 循环中缺少将 name 连接到 full_name 的一行：

full_name = name.lower()

将此添加到您的 while 循环中，就在 input() 调用下方，就像您在文件顶部所做的那样。

在您的 while 循环中，它应该说：

name = input('Enter your full name: ')
full_name = name.lower()

这至少会让你的程序运行得更远！

另外，请注意您的程序的逻辑可能有缺陷...您逐步检查 CSV 的每一行，检查一个人的姓名。这意味着如果您在 CSV 文件中有多个条目（即 - CSV 文件包含的不仅仅是一个人的信息），您只能真正访问列表中的第一个条目。您可能应该提示输入用户名，然后遍历 CSV 的每一行以检查匹配项。仅当整个 CSV 中没有匹配项时，您才应该要求另一个名称...只要看看...

Answer 3

在此代码中，您使用 name 获取名称，但后来您使用 full_name

 while (' '.join((row[0], row[1]))).lower() != full_name.strip():
        print('Name is not in system')
        name = input('Enter your full name: ')

你应该只使用full_name（它需要lower()）

 while (' '.join((row[0], row[1]))).lower() != full_name.strip():
        print('Name is not in system')
        full_name = input('Enter your full name: ').lower() # <-- full_name

或将name 转换为full_name

 while (' '.join((row[0], row[1]))).lower() != full_name.strip():
        print('Name is not in system')
        name = input('Enter your full name: ')
        full_name = name.lower() # <-- full_name
