I have a Dataframe with 1 row. I want to transpose it and give a name to the resulting column:
Have:
a b c
1 2 3
Want:
newname
1
2
3
I have found two ways for achieving this, which run without error when executed alone. However, when executed by a Dash app I get "Length mismatch: Expected axis has 0 elements, new values have 1". How can I fix this?
#Method 1
df = pd.DataFrame(np.array([[1, 2, 3]]), columns=['a', 'b', 'c'])
df.index = ['newname']
df = df.T
df = df.reset_index().newname
#Method 2
df = pd.DataFrame(np.array([[1, 2, 3]]), columns=['a', 'b', 'c'])
df = df.T
df.columns = 'newname'
df = df.reset_index().newname
