Cannot rename Columns in df

[deanhystad]

You must have an error in your column names, cause it works fine for me.

import pandas as pd

df = pd.DataFrame({"Visual ID": ["A", "B", "C", "D"],"VR Duration(Days)": [1, 2, 3, 4]})
df = df.rename(columns={"Visual ID": "Visual_ID","VR Duration(Days)": "VR_D"})
print(df)

Output:
  Visual_ID  VR_D
0         A     1
1         B     2
2         C     3
3         D     4

Look for trailing spaces.

import pandas as pd

df = pd.DataFrame({"Visual ID ": ["A", "B", "C", "D"],"VR Duration(Days) ": [1, 2, 3, 4]})
df = df.rename(columns={"Visual ID": "Visual_ID","VR Duration(Days)": "VR_D"})
print(df)

Output:
  Visual ID   VR Duration(Days) 
0          A                   1
1          B                   2
2          C                   3
3          D                   4
