Data analysis with list in python

I have a list in txt with the following data:

lista.txt 

AC;12;733559;8476515;11.57

Where each column works, respectively: UF, CODE, POPULATION, GDP, PIBPERCAPITA

When reading this file, I need to have the program return a menu with functions like:

  • View the data a specific UF
  • show data for some specified UF
  • Or show statistics like (average, minimum value and maximum value)

But I do not know where it goes, like reading a column. I do not know what the function in python would be. If anyone can give me a way it's already a lot of help.

I have my code like this: 

#enconding utf-8

import os
import platform

plataforma = platform.system()

if (plataforma == "Windows"):
    os.system("cls")
else:
    os.system("clear")

arquivo = open("C:\python\lista.txt", "r")
texto = arquivo.read()

dados = []
with open("C:/python/lista.txt") as lista:
    for linha in lista:
        if(linha.strip() != ''):
            coluna = [i.strip() for i in linha.split(' ')[:3:3]]
            dados.append(coluna)
print(dados)

I can print but it all comes out messy. I got this code here on the site.

You need the pandas module. To install run the command: 

pip install pandas

then import: 

import pandas as pd

To read the file, use the read_csv function. : 

df = pd.read_csv('lista.txt', delimiter=";",
       names=["UF","CODIGO", "POPULACAO","PIB","PIBPERCAPITA"])

If you give a print it will have the following output: 

    UF  CODIGO  POPULACAO         PIB  PIBPERCAPITA
0   AC      12     733559     8476515         11.57
1   AL      27    3120494    24574808          7.87
2   AM      13    3483985    59779292         17.17
3   AP      16     669526     8265965         12.36
4   BA      29   14016906   154340458         11.01
5   CE      23    8452381    77865415          9.22
6   DF      53    2570160   149906319         58.49
...

Complete code: 

#enconding utf-8
import pandas as pd
df = pd.read_csv('lista.txt', delimiter=";",
       names=["UF","CODIGO", "POPULACAO","PIB","PIBPERCAPITA"])
print(df)

I made a simple function that reads the file and returns a list with the desired state data. From there you can do calculations, statistics, or whatever you want with the data. 

def retornar_informacoes_estado(diretorio_txt, uf):

    try:
        arquivo = open(diretorio_txt, 'r')
        dados_arquivo = arquivo.read()
        arquivo.close()

        dados_arquivo = dados_arquivo.split('\n')

        tamanho_dados = len(dados_arquivo)

        for i in range(tamanho_dados):

            estado = dados_arquivo[i].split(';')

            if(estado[0] == uf):
                return estado

    except:
        return False

The function reads the file and separates each line into a list. Then it separates each data from a state into a list called state, then checks if there is any state according to the input of the parameter then returns that list with the state data.
