Saya melakukan beberapa praktik kode dan menerapkan penggabungan bingkai data saat melakukan ini mendapatkan peringatan pengguna
/usr/lib64/python2.7/site-packages/pandas/core/frame.py:6201: FutureWarning: Mengurutkan karena sumbu non-penggabungan tidak sejajar. Versi panda yang akan datang akan berubah menjadi tidak mengurutkan secara default. Untuk menerima perilaku masa depan, berikan 'sort = True'. Untuk mempertahankan perilaku saat ini dan membungkam peringatan, berikan sortir = False
Pada baris kode ini: Bisakah Anda membantu mendapatkan solusi dari peringatan ini.

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned.
apa itu anon-concatenation axis
dan seperti apa hasilnya? apakah kolom a dan kolom b akan tidak cocok? atau hanya urutan kolomnya saja yang berbeda?is not aligned
artinya - bisakah Anda mengomentarinya?aligned
berarti bahwa level pada sumbu adalah sama: jika ada perbedaan dalam bentuk apa pun, mereka tidak lagialigned
dan akan memicu perilaku ini (misalnya jika level sumbu adalah['c','b','a']
dan['a']
)level
sini berpotensi membingungkan karenalevel
memiliki arti khusus untuk dataframes pandas ketika ada MultiIndex. Dari yang saya pahami,aligned
dalam konteks ini mengacu pada urutan indeks baris / kolom. Jadi jika urutan indeks sumbu non-penggabungan berbeda untuk dua bingkai Anda, maka Anda dapat menentukan apakah akan mempertahankan urutan di bingkai pertama yang dilewati, dan mengurutkan bingkai kedua agar cocok, atau untuk mengurutkan indeks KEDUA bingkai sebelum penggabungan. Ini juga merupakan area yang membingungkan bagi saya, jadi koreksi diterima!tuple(df1.columns) == tuple(df2.columns)
. Sumbu non-penggabungan adalah sumbu (baris atau kolom) yang sejajar dengan jahitan di mana DataFrames sedang digabungkan.Jawaban jezrael bagus, tetapi tidak menjawab pertanyaan yang saya miliki: Apakah mendapatkan tanda "urutkan" yang salah akan mengacaukan data saya dengan cara apa pun? Jawabannya tampaknya "tidak", Anda baik-baik saja.
from pandas import DataFrame, concat a = DataFrame([{'a':1, 'c':2,'d':3 }]) b = DataFrame([{'a':4,'b':5, 'd':6,'e':7}]) >>> concat([a,b],sort=False) a c d b e 0 1 2.0 3 NaN NaN 0 4 NaN 6 5.0 7.0 >>> concat([a,b],sort=True) a b c d e 0 1 NaN 2.0 3 NaN 0 4 5.0 NaN 6 7.0
