While循环未输出正确的数据

Question

So I made corrections to my code as you all suggested. I'm able to get into the loop however once I input a correct name I'm still not able to get out of it. Any suggestions? Here's what I got:

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')

Here's the result when I give an input: fyi. Steve Miller is not in the csv file so that first response is correct. However, Sri Mantri is in the file and it should continue on and print out all the listings under her name.

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

Here's what the output should look like when the code runs.

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

Answer 1

Inside this code you use name to get name but later you use full_name

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

You should use only full_name (and it needs 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

Or convert name to 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

You're missing a line in your while loop that connects name to full_name:

full_name = name.lower()

Add this in your while loop, just below the input() call, like you have towards the top of your file.

Inside your while loop, it should say:

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

That will get your program to run, further, at least!

Also, please note that the logic of your program is probably flawed... You step through each line of the CSV, checking for a person's name. That means that if you have more than one entry in the CSV file, (ie - the CSV file holds more than just one person's info), you're only really able to access the first in the list. You should probably prompt for a username, THEN run through each row of the CSV to check for a match. Only if there is no match in the entire CSV should you ask for another name... Just give it a look...

If you are actually interested in other solutions go for my answer else just skip it. With pandas it is more easier to solve your need.

So I have a CSV file("names.csv") with this values in it,

Name    Hours
Sri Mati    1
Some Name   2

Here is the code:

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")

Sample Input and Output:

Enter your name: Steve Miller
Name not there

Next run,

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]]
