Why does if statement iteration return ambiguous series bool?

I'm quite new to python. I am trying to iterate through list columns using an 'if' statement with 2 conditions. The return statement I keep getting is "The truth value of a Series is ambiguous (when iterating through a series using if statement"

Below is my code (the data frame consists of app data from Google Play Store)

import pandas as pd
df = pd.read_csv("googleplaystore.csv")
df.tail()

df["Rating"].fillna(value = '0.0', inplace= True)

medical_app_ratings = []

for row in df[1:]:
    rating = df.Rating
    genre = df.Genres
    if genre == "Medical":
        medical_app_ratings.append(rating)

ValueError                                Traceback (most recent call last)
<ipython-input-154-51c7806c01da> in <module>
      5     rating = df.Rating
      6     genre = df.Genres
----> 7     if genre == "Medical":
      8         medical_app_ratings.append(rating).bool()
      9 

~\anaconda3\lib\site-packages\pandas\core\generic.py in __nonzero__(self)
   1477     def __nonzero__(self):
   1478         raise ValueError(
-> 1479             f"The truth value of a {type(self).__name__} is ambiguous. "
   1480             "Use a.empty, a.bool(), a.item(), a.any() or a.all()."
   1481         )

ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

If anyone could please tell me what I am doing wrong I would truly appreciate it.
