Python 使用Robot Framework读取CSV文件并从第n列中查找值

请帮我找到你的答案 使用Robot Framework读取CSV文件并从第n列中查找值 我不想使用excel库

我有一个csv文件，有5列和10000行 想要使用robot framework从第3列和7000行中查找值，我将如何直接查找值

我在下面进行了尝试，获得了一些价值，但循环执行了n次，这很耗时，可能会造成性能问题

${value1}   Create List             
${FILE_CONTENT} Get File    C:\\abcd1.csv           
Log File Content: ${FILE_CONTENT}               
@{LINES}    Split to Lines  ${FILE_CONTENT}         
Remove From List    ${LINES}    0           
:FOR    ${LINE} IN  @{LINES}        
     Log    ${LINE}         
     @{ROWS}    Split String    ${LINE} separator=, 
     ${VALUE}   Get From List   ${ROWS} 2   
     Log    ${VALUE}            
     ${value2}  Convert To String   ${VALUE}        
     Run Keyword If     ${value2} == 1400000    Exit For Loop       
     Append To List ${value1}   ${value2}           
     Log    ${value1}

首先，我试着按照我给你的建议使用内置库

github.com/s4int/robotframework-CSVLibrary

我遇到了一些错误，这可能是因为我的data.csv的格式，但并没有足够的时间来调试它

我用python为您的解决方案创建了一个自定义库，您可以在工作中使用它

data.csv

Name,Age,region,country,Marks
pankaj,22,delhi,india,45
neeraj,32,noida,india,75

python代码使用csv模块解析此数据，并返回第n行和第n列的值

import csv
#Previous function to go to nth row and nth column
def go_to_nth_row_nth_column(File,row_no,col_no):
    inputFile = File
    row_no=int(row_no)
    col_no=int(col_no)
    with open(inputFile) as ip:
        reader = csv.reader(ip)
        for i, row in enumerate(reader):
            if i == row_no:      # here's the row 
                #print row[col_no] # here's the column
                return row[col_no]

#Function to find the string values, in case of duplicate occurrence as well
def search_cell(File,search_string):
    inputFile = File
    search_position=[]  #empty list which will later store row,column occurences
    with open(inputFile) as ip:
        reader = csv.reader(ip)
        for i, row in enumerate(reader):
            for j, column in enumerate(row):
                if search_string in column:      # here's the row 
                    #print((i,j))
                    search_position.append((i,j)) #this will create list of list i.e. list of row,columns in case of multi occurences
                    #return (i,j)   
    return search_position

您可以在robot文件中将其用作库，如下所示

*** Settings ***
Library    csv2.py



 *** Test Cases ***
Test
    Check row column
    Search String

*** Keywords ***
Check row column
    ${result} =    go_to_nth_row_nth_column    data.csv    2    1
    log  ${result}

Search String
    ${result1}=    search_cell    data.csv    india
    log  ${result1}

我得到的答案是唯一的

['40'，'第二项'，'300']

我希望@pankaj建议的两个包含300个的列都使用带有以下代码的库。此代码查找变量

${value_to_find}

，如果找到，则返回，否则继续循环并记录消息。如果要在单个列中查找变量，可以自定义

验证变量

关键字范围/循环

将代码添加到你的问题中并正确设置格式。你能将代码复制并粘贴到问题本身中吗understand@pankajmishra是否请检查您是否检查了RF@pankajmishra中的CSV库，但我如何从第n个单元格中找到值这太棒了，但我试图验证该值，比如说我有值“abc”在一个变量和csv中，某些列中存在相同的值，我想通过查看csv来验证我将如何找到该值。例如：当我们执行ctrl+F并从列中找到我要应用的逻辑值时，请帮助请再次查看我的示例，首先理解它，然后试着按照你的要求实现一些逻辑用合适的fromatting发布你的代码，这很难理解发布的请检查和帮助您的回答帮助，因为我对编码和构建逻辑不熟悉，请再向您请求一件事，请帮助我想搜索固定列中的值，即我将直接提供的列num，并想搜索字符串、数字，我如何获得该值请帮助thanks@pankaj米什拉，请检查以上我得到的，但如果我想要两者，那么该怎么办谢谢
