Attempting to compare values in a list to a string to determine if they match

Question

I am attempting to compare the values within a string to values in a list. If the values match, a third list is addended with either a 1 or 0.

Current attempt is to examine each value within the 2 strings. If the entries within the string match, a hash mark is tallied in a third string (0 or 1). I am unable to make the comparison function work - It's not returning any values.

Recent edit: I cannot link to the assignment page, but i can post an image of the problem.

Code is below:

> #list values
landing_outcomes =['True ASDS      41\nNone None      19\nTrue RTLS      14\nFalse ASDS      6\nTrue Ocean      5\nFalse Ocean     2\nNone ASDS       2\nFalse RTLS      1\nName: Outcome, dtype: int64']

> #string values
bad_outcomes = {'False ASDS', 'False Ocean', 'False RTLS', 'None ASDS', 'None None'}


landing_class = []


> #comparison
if any (x in [landing_outcomes] for x in [bad_outcomes]):
landing_class += 0

else:
landing_class += 1


print (landing_class)

Based on your edit (the image you added)...

• landing_outcomes is a pandas Series (A column from a dataframe)
• the index of which is the list of Outcomes
• you want to check the dataframe against the set
• which is the opposite of your question

import pandas as pd

landing_outcomes = pd.Series(
  [41, 19, 14, 6, 5, 2, 2, 1],
  index=['True ASDS', 'None None', 'True RTLS', 'False ASDS', 'True Ocean', 'False Ocean', 'None ASDS', 'False RTLS'],
  name='Outcome'
)

bad_outcomes = {'False ASDS', 'False Ocean', 'False RTLS', 'None ASDS', 'None None'}

print() 
print(landing_outcomes)
print()
print(bad_outcomes)

landing_class = (~landing_outcomes.index.isin(bad_outcomes)).astype(int).tolist()

print()
print(landing_class)

That Series object has an isin() method that returns a new Series with True or False on each row.

Using ~ inverts the boolean values (so giving the result of "is not in").

Casting a boolean to an integer (with astype) turns those booleans in to 1s and 0s.

Then tolist() turns the pandas Series into a regular python list.
