{"library":"Pandas","prompt":"Problem:\nI need to rename only the first column in my dataframe, the issue is there are many columns with the same name (there is a reason for this), thus I cannot use the code in other examples online. Is there a way to use something specific that just isolates the first column?\nI have tried to do something like this\ndf.rename(columns={df.columns[0]: 'Test'}, inplace=True)\nHowever this then means that all columns with that same header are changed to 'Test', whereas I just want the first one to change.\nI kind of need something like df.columns[0] = 'Test'  but this doesn't work.\n\n\nA:\n<code>\nimport pandas as pd\n\n\ndf = pd.DataFrame([[1, 2, 3], [4, 5, 6], [7, 8, 9]], columns=list('ABA'))\n</code>\nresult = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
