While循环未输出正确的数据

Question

因此，正如大家所建议的，我对我的代码进行了更正。 我可以进入循环，但是一旦输入正确的名称，我仍然无法摆脱它。 有什么建议么？ 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')

当我输入时，结果如下：fyi。 Steve Miller不在csv文件中，因此第一个响应是正确的。 但是，Sri Mantri已保存在文件中，应该继续并以她的名字打印所有清单。

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

这是代码运行时输出的外观。

Enter your full name: Sri mantri
This is sri mantri full hours report:

Answer 1

在此代码内，您使用name来获取名称，但稍后使用full_name

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

您应该只使用full_name （并且需要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

Answer 2

您在while循环中缺少将name连接到full_name的行：

full_name = name.lower()

将此添加到您的while循环中，就在input（）调用的下面，就像您将文件顶部放置的那样。

在while循环中，它应该说：

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

至少，这将使您的程序进一步运行！

另外，请注意，您的程序逻辑可能存在缺陷……您逐一浏览CSV的每一行，检查一个人的名字。 这意味着，如果CSV文件中有多个条目（即-CSV文件包含的信息不止一个人），则您实际上只能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的每一行以检查是否匹配。 仅当整个CSV文件中都没有匹配项时，您才需要输入其他名称...看看吧...

如果您实际上对其他解决方案感兴趣，请直接回答。 使用熊猫，可以更轻松地解决您的需求。

所以我有一个CSV文件（“ names.csv”），其中包含此值，

Name    Hours
Sri Mati    1
Some Name   2

这是代码：

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")

样本输入和输出：

Enter your name: Steve Miller
Name not there

下一轮

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]]
