如何在 python dataframe 中的列和行之间进行转换？

Question

scenario 1

original dataframe:

ab c defg

new dataframe:
a
b
c
d
e
f
g

scenario 2

original dataframe:

gfed c ba

new dataframe:
a
b
c
d
e
f
g

My question is how to perform the above transformations?

Answer 1

Try the following:

import pandas as pd

df = pd.DataFrame(columns=list('abcdefg'))
df_new = pd.DataFrame([col for col in df.columns], columns=['column_to_rows'])

print(df_new)

Answer 2

just add ".T" to your dataframe.

pd.DataFrame(['a','b','c', 'd', 'e', 'f', 'g'])
Out[99]: 
   0
0  a
1  b
2  c
3  d
4  e
5  f
6  g

pd.DataFrame(['a','b','c', 'd', 'e', 'f', 'g']).T

Out[100]: 
   0  1  2  3  4  5  6
0  a  b  c  d  e  f  g
