Question

我是一位网络工程师，试图使用Python学习编程。我对任何形式的编程都是新手。

我正在尝试从.csv文件中搜索列1中的值，并返回对应列的字符串。执行程序时，它将遍历所有单元格，显示每个单元格的结果。我想要的是，如果用户输入数字，则需要搜索列表，一旦找到匹配项，则返回下一列的字符串。如果用户输入的值不存在，则返回打印语句。

import csv
import sys

fileName = 'sip.csv'
READ = 'r'
WRITE = 'w'

enter_code = input('Enter The Sip Response Code: ')
with open(fileName, READ) as myXLfile:
    dataFromFile = csv.reader(myXLfile)
    for currentRow in dataFromFile:
        if enter_code == currentRow[0]:
            print("The SIP Response Code you entered is: " + enter_code)
            print("The SIP Message is:  " + currentRow[1])
            print("Meaning:  " + currentRow[2])
            break
        if enter_code != currentRow[0]:
            print("Im Sorry, I Do not have this Response Code")
    else:
        print("Thank You and Goodbye")

结果：

Enter The Sip Response Code: 200
Im Sorry, I Do not have this Response Code
Im Sorry, I Do not have this Response Code
Im Sorry, I Do not have this Response Code
Im Sorry, I Do not have this Response Code
Im Sorry, I Do not have this Response Code
Im Sorry, I Do not have this Response Code
The SIP Response Code you entered is: 200
The SIP Message is:  OK
Meaning:  The request has been successfully processed and the result of the request is transmitted in the response.

Answer 1

您的意思是这样的：

import csv

fileName = 'sip.csv'
READ = 'r'
WRITE = 'w'
check = True

enter_code = input('Enter The Sip Response Code: ')
with open(fileName, READ) as myXLfile:
    dataFromFile = csv.reader(myXLfile, delimiter=";")
    for currentRow in dataFromFile:
        if enter_code == currentRow[0]:
            print("The SIP Response Code you entered is: " + enter_code)
            print("The SIP Message is:  " + currentRow[1])
            print("Meaning:  " + currentRow[2])
            check = False
            break
    if check:
        print("Im Sorry, I Do not have this Response Code")
    else:
        print("Thank You and Goodbye")

Answer 2

类似的东西应该对您有用。

# Select All From CSV File Where

import csv
# Asks for search criteria from user
search_parts = input("Enter search criteria:\n").split(",")
# Opens csv data file
file = csv.reader(open("C:\\your_path\\test.csv"))
# Go over each row and print it if it contains user input.
for row in file:
    if all([x in row for x in search_parts]):
        print(row)
