Why does Python give recursion error for using a method that belongs to an external package

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I'm trying to build functions that calculate the mean, median and mode of a given list. For mode only, I'm using from statistics import mode (everything else is manual) but when it comes to outputting the result, only the line of code using the mode() method gives me a recursion error.

This is my code:

import pandas as pd

from statistics import mode



dataFrame = pd.read_csv("https://archive.ics.uci.edu/ml/machine-learning-databases/forest-fires/forestfires.csv")



area = dataFrame['area'].tolist()

rain = dataFrame['rain'].tolist()



months = dataFrame['month'] = dataFrame['month'].map({'jan': 1, 'feb': 2, 'mar': 3, 'apr': 4, 'may': 5, 'jun': 6, 'jul': 7, 'aug': 8, 'sep': 9, 'oct': 10, 'nov': 11, 'dec': 12}).tolist()



def mean(numbers):

  meanOfNumbers = (sum(numbers))/(len(numbers))

  return meanOfNumbers



def median(numbers):

  if(len(numbers) % 2 == 0):

    medianOfNumbers = (numbers[int((len(numbers))/2)] + numbers[int((len(numbers))/2-1)])/2

  else:

    medianOfNumbers = numbers[int((len(numbers)-1)/2)]

  return medianOfNumbers



def mode(numbers):

  modeOfNumbers = int(mode(numbers))

  return modeOfNumbers



print("The mean of the months is: " + str("%.2f" % round(mean(months))))

print("The median of the months is: " + str("%.2f" % round(median(months))))

print("The mode of the months is: " + str(mode(months)))

And this is the error:

The mean of the months is: 7.00

The median of the months is: 8.00

If you must have a function called mode and also make use of statistics.mode, you can use its qualified name to distinguish which one you mean.

import statistics



...



def mode(numbers):

    return int(statistics.mode(numbers))
