如何在csv中修复我的Pandas Dataframe输出

Question

When trying to run the following code I am not getting expected results. I want the output to span multiple columns.

It looks like it is throwing quotation marks around the data like this

"column1, column2, column3"
"sdf,e,sd"

import pandas as pd
outputPath = r'C:\Users\Jfairfield\Desktop\output.csv'
testPath = r'C:\Users\Jfairfield\Desktop\test.csv'
csvData = pd.read_csv(testPath, 'Sheet1')
csvData.to_csv(outputPath, index=False)

Input:

Input as Text
column1, column2, column3
sdf,e,sd

Current Output:

Answer 1

outputPath = r'C:\Users\xxx\Desktop\Python fo excel\mycsv - Copy.csv'
testPath = r'C:\Users\xxx\Desktop\Python fo excel\mycsv.csv'
csvData = pd.read_csv(testPath,  sep=',', engine='python')
print(csvData)
csvData.to_csv(outputPath, index=False, sep=',')

output

     A  B   C
0  sdf  e  sd

Answer 2

It's likely you have a quoted lines in the text file, which escapes the delimiter while reading data in, you can try set quoting=3 (Quote None) to avoid the behavior:

Example :

stripQuote = lambda x: x.strip('"')
​
df = pd.read_csv(StringIO("""
"a,b,c"
"d,e,f"
"""), quoting=3, converters={0: stripQuote, 2: stripQuote})
​
df.columns = ['a','b','c']

df
#   a   b   c
#0  d   e   f
