How do I read only certain columns in pandas from excel?

I've been reading a column from a list of files using pandas.

Readexcel() for the last few days but it has become apparent I'd need to be able to stop reading certain columns which is a problem since most of my data doesn't have all three columns (start, finish, and total) or any of them so I need to be able to read only what I need. I can only seem to find examples of extracting columns based on index in the examples I find so far.

Eg:
Import numpy as np. Import pandas as pd. Df = pd.readexcel('testdata.sortvalues(ascending=True)

You could use df.iloc, assuming the dataframe has been sorted by date range columns: df = pd.readexcel('testdata.xlsx')

Def filterdf(df): start = df.eq('a') & df.eq('b')
startstop = df.

How do I read certain columns in pandas?

I am trying to read certain columns from a csv file.

This is how the data is stored in the file. Name,Value1,Value2,Value3,Value4,Value5,Value6,Value7,Value8,Value9. Name1,Value11,Value12,Value13,Value14,Value15,Value16,Value17,Value18,Value19. Name2,Value21,Value22,Value23,Value24,Value25,Value26,Value27,Value28,Value29. Name3,Value31,Value32,Value33,Value34,Value35,Value36,Value37,Value38,Value39. What I am trying to achieve is to read the data starting from the second column and until the last column. I have tried. Import pandas as pd. Df = pd.readcsv('test.

Thank you! pandas.readcsv can accept a list of columns: df = pd.readcsv('test.

You can use Pandas' skiprows function to do this. To do this, you just need to create a list of the columns you want to read from your CSV file, then pass the list of columns to the skiprows argument.readcsv('test.

How do I skip column names in pandas read excel?

Hi and thank you for taking the time to look at my problem.

Let me first explain what I want to achieve. I am not sure if I did it correctly. It would be most interesting to hear what is wrong with my current code.

Here is my Problem: I have an Excel-File with a lot of (3-4) Columns and some rows which I want to skip. Let us make a short example to see my issue. Excel File: Output: def test(): import pandas as pd. source = open('1.xlsx') df = pd.readexcel(source, usecols=range(2,7)) print(df). Thank you very much! This is a hack, but if you have xlrd then do this : from xlrd import openworkbook. Import xlrd. Wb = openworkbook('1.xlsx') sheetname = 'MySheetName'. Sheet = wb.sheetbyindex(0) print 'Sheet data size'. Print sheet.size def writeheader(headers): row = 0. for header in headers: sheet.nrows): data = sheet.cellvalue(row, 0) valfname = sheet.cellvalue(row, 1) vallname = sheet.cellvalue(row, 2) valtitle = sheet.cellvalue(row, 3) .

For each iteration above, you can check the sheet name is equal to MySheetName.
