I’m stuck on trying to open, read and list the apple and android dataset. I keep getting the below error message stating “android_header” is not defined.
My Code:
What I expected to happen:
Sorry I couldn’t post more than one image. I expected to have this dataset listed out.
What actually happened:
I kept getting the following error:
NamError: name “andorid_header” is not defined. It seems it is to me, so I don’t know what I’m missing.
Hello @redkraftllc and welcome to the community!
First, avoid posting images of the code. When you post a well-formatted piece of code it is easier for people to help you. If you don’t know how to that, take a look at the Technical Question Guidelines. You should also post the entire description of the error raised.
With the information you provided, I can see the problem is a typo, since the error says:
NamError: name "andorid_header" is not defined
At some point, you typed andorid_header instead of android_header. But as you did not post the full error, I cannot know which line of code is causing it. In fact, as you posted an image of two cells, I do not even know which cell is raising the error.
When you format your question properly, you have more chances of receiving a fast, accurate answer.
Thank you for your response and for sharing useful tips on how to post a topic. It’s my first time posting here so kindly bear with me. Here’s the full code below. I wish it was a misspelling, but it isn’t, as I accidentally typed that on here.
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 Apple Store Data Set ##
opened_file = open("AppleStore.csv")
read_file = reader(opened_file)
ios = list(read_file)
ios_header = ios[0]
ios = ios[1:]
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 between rows
if rows_and_columns:
print('Number of rows:', len(dataset))
print('Number of columns:', len(dataset[0]))
print(android_header)
print('\n')
explore_data(android, 0, 3, True)
##This happens after I run the code above##

NameError: name 'android_header' is not definedThat’s OK, but please notice that your code is not properly formatted yet.
Your problem is in the following line:
print(android_header)
The error says the variable android_header is not defined, but you defined in the first cell. So I’m guessing you probably ran the second cell before running the first one.
Perfect! How right you are. I can’t believe the answer was that obvious. Thanks so much!
