Data Science - Missing Numbers Project

your output and the expected output are not the same, at the end of the expected output there is also: dtype: float64 use pd.Series instead of DataFrame no need to print each element one by one lst_df = pd.Series(lst) final = lst_df.fillna(lst_df.mean()).round(1) print(final)

import numpy as np import pandas as pd lst = [float(x) if x != 'nan' else np.NaN for x in input().split()] lst_df = pd.Series(lst) abdullah = lst_df.fillna(lst_df.mean()).round(1) print(abdullah)

import numpy as np import pandas as pd lst = [int(x) if x != 'nan' else np.nan for x in input().split()] df = pd.Series(lst) df = df.fillna(df.mean()).round(1) print(df) hi, all i tried this code i cleared two test cases but the remaining are hidden please help to solve this

Akash Poovan Use float(x) instead int(x) because we still consider about the decimal too

This work nice: import numpy as np import pandas as pd lst = [float(x) if x != 'nan' else np.nan for x in input().split()] df = pd.Series(lst) df = df.fillna(df.mean()).round(1) print(df)

Thanks a lot dude. I ll try that. I am drinking beers now. But ll try that later.

Dude. Even drunk I tried that right now and it worked. Thanks a lot. May Odin receive you in Valhalla with Meat and Ale.

Bahha🐧 Thanks! Had the same problem

everyone in this project used fillna attiribute. but so far , as beginners , we didnt learn this attribute. in this condition; 1) how can i find there is a attribute for this function? ( yes i know i can find it in forums, but it wont happen always.) is there any easy way to find out? 2)to solve this problem without using "fillna", i need to know what is the value of np.nan elements. for example for x in lst : if x != "nan": #it always true even if the value is np.nan ... ... could you help tahnks sory for my language :(

Did someone know how lst = [float(x) if x != 'nan' else np.NaN for x in input().split()] Function works? I still don't understand

Sylvanast Code just look the input and if it is not "Nan" returns float x else return np.nan

To answer Sylvanast question lst = [float(x) if x != 'nan' else np.NaN for x in input().split()] this function works by splitting up a string of values and turning the values into a floating point (values) if x does not equal 'nan' else if 'nan' replace with np.NaN (Not a Number) for every value in the input

Use df.fillna(df.mean(), inplace=True) if you don't use df = df.fillna(.....)

what the.. you guys give answers using fillna, which is not include the course. I'm a beginner, as many others, how can we resolve this challenge while we are not taught about it? I tried: new_lst = [i if i != 'NaN' else mean for i in lst] but ofcourse it failed. I cannot figure out what 'np.NaN' value is, even I tried: new_lst = [i if i != np.NaN else mean for i in lst] or many things like null, '', ' ', None,... still failed

try this dummy code: import numpy as np import pandas as pd lst = [float(x) if x != 'nan' else np.nan for x in input().split()] din = pd.Series(lst) din = din.fillna(df.mean()).round(1) print(din)

import numpy as np import pandas as pd lst = [float(x) if x != 'nan' else np.NaN for x in input().split()] ds = pd.Series(lst) print(ds.fillna(ds.mean()).round(1))

import numpy as np import pandas as pd lst = [float(x) if x != 'nan' else np.NaN for x in input().split()] nplst=np.array(lst) #convert input to numpy array lst=list(nplst[~np.isnan(nplst)]) #removing nan values to calculate mean x=round(np.array(lst).mean(),1) #the mean calculation y=np.nan_to_num(nplst,nan=x) #replacing the nan with calculated mean nplst=pd.Series(y) print(nplst)
