How can I replicate rows in Pandas?

My pandas dataframe looks like this:

   Person  ID   ZipCode   Gender
0  12345   882  38182     Female
1  32917   271  88172     Male
2  18273   552  90291     Female

I want to replicate every row 3 times like:

   Person  ID   ZipCode   Gender
0  12345   882  38182     Female
0  12345   882  38182     Female
0  12345   882  38182     Female
1  32917   271  88172     Male
1  32917   271  88172     Male
1  32917   271  88172     Male
2  18273   552  90291     Female
2  18273   552  90291     Female
2  18273   552  90291     Female

And of course, reset the index so it is:

0
1
2
...

I tried solutions such as:

pd.concat([df[:5]]*3, ignore_index=True)

And:

df.reindex(np.repeat(df.index.values, df['ID']), method='ffill')

But none of them worked.
