Question

嘿伙计们我正在使用python我只需要知道我的代码中我做错了什么这是代码的剪辑，这是我猜的错误：

Uni2Rows = []
R2Rows = 0
for rows in filter:
     R2Rows += 1
     if R2Rows > 3 and R2Rows < 34 and rows[0] is not '':
        Uni2Rows.append(rows)

GradUnderGrad = {'No.': ('Company', 'Grad', 'UnderGrad')}
for i, out2put in enumerate(Uni2Rows):
    total = 0
    for roww in Uni2Rows [11:12]:
        if roww[out2put] is not '':
            total += 1
    GradUnderGrad.append(['No', twoColumns, UniRows[11], UniRows[12]])
 print(GradUnderGrad)

这是我整个程序的代码，我也说了我希望我的预期答案看起来如何，但我实际得到的是什么

####please dont copy straight up its like stealing an essay some things you cant really change theres only so many ways to do it 

 ##Code by Angel M Gonzalez 

import csv
with open('scratch.csv', 'r', errors='replace') as progfile:
    progfile.close()
a = open("scratch.csv")
filter = csv.reader(a)

# Step 2: Printing
 columns = { 0: 'Company', 1: 'Booth', 2: 'Full-Time', 3: 'Full-Time Visa Sponsor', 4: 'Part-Time', 5: 'Internship', 6: 'Freshman', 7: 'Sophomore', 8: 'Junior', 9: 'Senior', 10: 'Post-Bacs', 11: 'MS', 12: 'PhD', 13: 'Alumni', }
for i in columns:
    print(i, columns[i])

 # Step 3: Filtering and Formatting
 UniRows = []
 RRows = 0
 for rows in filter:
   RRows += 1
   if RRows > 3 and RRows < 34 and rows[0] is not '':
       UniRows.append(rows)

#Step 4 Expected output
employersSummary = {'No.': ('Column', 'Sum')}
for output in range(14):
    total = 0
    for rrows in UniRows:
        if rrows[output] is not '':
            total += 1
    employersSummary[output] = (columns[output], total)
 print(employersSummary)

#Step 4 continued
twoColumns = {
0: 'AIG',
1: 'Baylor College of Medicine',
2: 'CGG',
3: 'Citi',
4: 'ExxonMobil',
5: 'Flow-Cal Inc.',
6: 'Global Shop Solutions',
7: 'Harris County CTS',
8: 'HCSS',
9: 'Hitachi Consulting',
10:'HP Inc.',
11: 'INT Inc.',
12: 'JPMorgan Chase & Co',
13: 'Leidos',
14: 'McKesson',
15: 'MRE Consulting Ltd.',
16: 'NetIQ',
17: 'PROS',
18: 'San Jacinto College',
19: 'SAS',
20: 'Smartbridge',
21: 'Sogeti USA',
22: 'Southwest Research Institute',
23: 'The Reynolds and Reynolds Company ',
24: 'UH Enterprise Systems',
25: 'U.S. Marine Corps',
26: 'ValuD Consuting LLC',
27: 'Wipro',}
for i in twoColumns:
    print(i, twoColumns[i])

#Step 4 continued

Uni2Rows = []
R2Rows = 0
for rows in filter:
    R2Rows += 1
    if R2Rows > 3 and R2Rows < 34 and rows[0] is not '':
        Uni2Rows.append(rows)


GradUnderGrad = {'No.': ('Company', 'Grad', 'UnderGrad')}
for i, out2put in enumerate(Uni2Rows):
    total = 0
    for roww in Uni2Rows [11:12]:
        if roww[out2put] is not '':
            total += 1
    GradUnderGrad.append(['No', twoColumns, UniRows[11], UniRows[12]])
 print(GradUnderGrad)

这是我想要的最后一步结果：

No Company Grad UnderGrad
0 AIG, 1, 1
1 Baylor College of Medicine, 0, 0
2 CGG, 1, 0
3 Citi, 0, 1
4 ExxonMobil, 0, 1
5 Flow-Cal Inc., 0, 1
6 Global Shop Solutions, 0, 1
7 Harris County CTS, 1, 1
8 HCSS, 1, 1
9 Hitachi Consulting, 1, 1
10 HP Inc., 1, 1
11 INT Inc., 1, 1
12 JPMorgan Chase & Co, 0, 1
13 Leidos, 1, 1
14 McKesson, 0, 1
15 MRE Consulting Ltd., 1, 1
16 NetIQ, 0, 1
17 PROS, 1, 1
18 San Jacinto College
19 SAS, 1, 1
20 Smartbridge, 1, 1
21 Sogeti USA, 1, 1
22 Southwest Research Institute, 1, 1
23 The Reynolds and Reynolds Company 0 1 24 UH Enterprise Systems, 1, 1
25 U.S. Marine Corps, 1, 1,
26 ValuD Consuting LLC, 0, 1
27 Wipro, 0 
Total 17 26

但这就是我不断得到的东西而且令人讨厌：

 [No Company Grad UnderGrad]

我的问题是本科的最后一步我使用的是csv文件。有谁知道我做错了什么？我没有正确合并列我是否需要一个不同的代码，如果有人帮助我，请做我需要帮助。

为什么使用如此复杂的方法来读取某些行并找到所需的字符串。

以下是您可以使用的示例代码，以实现您的目标：

import csv
import re

import os

repeatCheck = []
dataTOWorkWith = []
print(os.getcwd())
with open('task2.csv', 'r') as csv_file:
    csv_reader = csv.reader(csv_file, delimiter=' ')
    idx = 0
    for line in list(csv_reader)[3:]:
            rowdata = ",".join(i for i in line)
            if "BOOTH" in rowdata :
                break
            if (not rowdata.startswith(","  or ".")) and (rowdata not in repeatCheck) and (rowdata != ""):
                dataTOWorkWith.append( str(idx) + "," + (re.sub('[^a-zA-Z0-9\n\.,]', ' ', rowdata )))
                idx+=1
                repeatCheck.append(rowdata)
with open('task4.csv', 'w') as csv_file:

    banner = "No Company Grad UnderGrad"
    csv_file.write(",".join(x for x in banner.split(" "))+"\n")
    print(banner)
    for data in dataTOWorkWith :
        rowToPrint  = " ".join(data.split(",")[0:2])+" "
        rowdataToAppend = ",".join(data.split(",")[0:2])+","
        underGrand = "".join(data.split(",")[7:10]).rstrip()
        Grand = "".join(data.split(",")[11:12]).rstrip()
        if Grand != "" :
            rowToPrint+=str(1)+" "
            rowdataToAppend+=str(1)+","
        else:
            rowToPrint += str(0) + " "
            rowdataToAppend += str(0) + ","

        if underGrand != "" :
            rowdataToAppend += str(1) + ","
            rowToPrint+=str(1)
        else:
            rowdataToAppend += str(0) + ","
            rowToPrint += str(0)
        grandUgrad = Grand + "," + underGrand
        print(rowToPrint)
        csv_file.write(rowdataToAppend+"\n")

<强>输出
