Convert yyyy-mm-dd to yyyy-ww in Python

Question

I'm trying to to convert yyyy-mm-dd into yyyy-ww .

How is this achieved for the following dataframe:

dates = {'date': ['2015-02-04','2016-03-05']}

df = pd.DataFrame(dates, columns=['date'])

print(df)
0   2015-02-04
1   2016-03-05
dtype: datetime64[ns]

I've tried using

YW = pd.to_datetime(df, format='%Y%W')

However without luck.
