Android App Analysis Importing Data Error

Screen Link: <!-- Enter URL of the screen below –>

My Code:

def explore_data(dataset, start, end, rows_and_columns=False):
    dataset_slice = dataset[start:end]
    for row in dataset_slice:
        print(row)
        print('\n') # adds a new (empty) line after each row
        
    if rows_and_columns:
        print('Number or rows:', len(dataset))
        print('Number of columns:', len(dataset[0]))

from csv import reader

### The Google Play data set ###
opened_file = open('googleplaystore.csv')
read_file = reader(opened_file)
android = list(read_file)
android_header = android[0]
android = android[1:]

### The App Store data set ###
opened_file = open('AppleStore.csv')
read_file = reader(opened_file)
ios = list(read_file)
ios_header = ios[0]
ios = ios[1:]

explore_data(android, 0, 3, True)

What I expected to happen:
I am not sure as I am just starting to do this. I reckon some sort of preview of the android data.

What actually happened:

UnicodeDecodeError                        Traceback (most recent call last)

      7 android_header = android[0]
      8 android = android[1:]

     25 class StreamWriter(Codec,codecs.StreamWriter):

UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 2755: character maps to <undefined>

This error comes up after running the open csv file attempts. Not sure why as the file is in the same directory as the Jupyter Notebook I opened. Any kindly provided guidance, be it specific to the problem or how to better post in the future would be well-received. Thank you.

@ejoseph13
Have you tried explicitly specifying the encoding ?

opened_file = open('googleplaystore.csv', encoding="utf8")
