Python os,glob and statistics

import os 
import glob

 print(os.getcwd()) # şuan üzerinde çalıştığımız dizini döner

 #komut satırında işlem yaptırma
os.system('ipconfig') 

 #py uzantılı dosyaları arayıp listeler
print(glob.glob("*.py"))

 #python ile istatistik hesapları yapılabilir.
import statistics

 veriGrubu=[12,63,85,63,45,19,12,98,25,12,14,154,12,91,19,2,5]

 #Bunu ortalama için yazmanıza gerek yok.Sadece toplamı görmek için yazdım.
print("  toplam : ",sum(veriGrubu)) 

 print("ortalama : ",statistics.mean(veriGrubu)) #ortalama hesabı

 print("  medyan : ",statistics.median(veriGrubu)) #medyan hesabı

 print("     mod : ",statistics.mode(veriGrubu)) #mod hesabı

 print(" varyans : ",statistics.variance(veriGrubu)) #varyans hesabı

Long-short-term-memory (LSTM) Word Prediction With PyTorch

LSTM Text Generation with PyTorch - Complete Guide LSTM Text Generation with PyTorch A comprehensive guide to building word-level language models with Long Short-Term Memory networks Introduction to LSTM Text Generation Long Short-Term Memory (LSTM) networks are a special kind of recurrent neural network (RNN) capable of learning long-term dependencies. They are particularly useful for sequence prediction problems like text generation, where the context from previous words is crucial for predicting the next word. Key Concepts Word-level modeling : Predicts the next word given previous words Embeddings : Dense vector representations of words ...
