Answer 1

Firstly make use of rstrip() method and split() method:

df['Devices']=df['Devices'].str.rstrip(';').str.split(';')
df['Purchase Date']=df['Purchase Date'].str.rstrip(';').str.split(';')

Finally use explode() method:

df_out=df.explode('Devices')
df_out['Purchase Date']=df['Purchase Date'].explode()

Now If you print df_out you will get your desired output
