Question

所以我建议你对我的代码进行更正。我能够进入循环但是一旦我输入正确的名称，我仍然无法摆脱它。有什么建议？这就是我得到的：

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：仅供参考。史蒂夫米勒不在csv文件中，所以第一反应是正确的。但是，Sri Mantri在文件中，它应该继续并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

这里是代码运行时输出的样子。

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

Answer 1

在此代码中，您使用name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循环中缺少一个将name连接到full_name的行：

full_name = name.lower()

在你的while循环中添加它，就在input（）调用的正下方，就像你在文件的顶部一样。

在while循环中，它应该说：

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

这将使您的程序至少进一步运行！

另外，请注意您的程序逻辑可能存在缺陷......您逐步浏览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文件只包含一个人的信息），您实际上只能访问列表中的第一个条目。您应该提示输入用户名，然后运行CSV的每一行以检查匹配项。只有当整个CSV中没有匹配时，您才会要求另一个名称......只需看看......

如果你真的对其他解决方案感兴趣，那就去找我的答案吧。使用pandas可以更轻松地解决您的需求。

所以我有一个CSV文件（“names.csv”），里面有这个值，

Name    Hours
Sri Mati    1
Some Name   2

以下是代码：

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")

示例输入和输出：

Enter your name: Steve Miller
Name not there

下一步，

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]]

虽然循环不输出正确的数据
