Python fill a list with the same string

Question

I have a pandas DataFrame and I would like to make a new column with the same string in each row.

Currently I'm doing this.

tag=[]
for x in xrange(len(preds)): #preds is a np.array, same length of df
    tag.append('MY STRING')
 df['TAG']=tag

I know there must be a smarter way to do this.

Any help is appreciated.

df['TAG'] = ['MY STRING'] * len(preds)
