Thank you Peter and Christ.
It is was a white space and the fix fixed it.
Many thanks.

Did you put these lines here using copy and paste? The fix below depends on
the assumption that your data is more like
size, w1, h1
512, 214, 26
123, 250, 34
...
> a=pd.read_csv("s1.csv", skipinitialspace=True).keys()
You should use the keys() method call for diagnosis only. The final script
that might work if your problem is actually space after the commas is
import pandas as pd
a = pd.read_csv("s1.csv", skipinitialspace=True)
a["test"] = a["h1"] + a["w1"]
print(a)
