Объедините два столбца фрейма данных Pandas
Опубликовано: 27 Марта, 2022
Давайте обсудим, как объединить два столбца фрейма данных в pandas python. Мы можем сделать это, используя следующие функции:
- concat ()
- добавить ()
- присоединиться()
Example 1 : Using the concat() method.
# importing the moduleimport pandas as pd # creating 2 DataFrameslocation = pd.DataFrame({"area": ["new-york", "columbo", "mumbai"]})food = pd.DataFrame({"food": ["pizza", "crabs", "vada-paw"]}) # concatenating the DataFramesdet = pd.concat([location, food], join = "outer", axis = 1) # displaying the DataFrameprint(det) |
Output :
Example 2 : Using the append() method.
# importing the moduleimport pandas as pd # creating 2 DataFramesfirst = pd.DataFrame([["one", 1], ["three", 3]], columns =["name", "word"])second = pd.DataFrame([["two", 2], ["four", 4]], columns =["name", "word"]) # concatenating the DataFramesdt = first.append(second, ignore_index = True) # displaying the DataFrameprint(dt) |
Output :
Example 3 : Using the .join() method.
# importing the moduleimport pandas as pd # creating 2 DataFrameslocation = pd.DataFrame({"area" : ["new-york", "columbo", "mumbai"]})food = pd.DataFrame({"food": ["pizza", "crabs", "vada-paw"]}) # concatenating the DataFramesdt = location.join(food) # displaying the DataFrameprint(dt) |
Output :
For the three methods to concatenate two columns in a DataFrame, we can add different parameters to change the axis, sort, levels etc.
