# Esse arquivo tem como intuito ensinar a importação e manipulação de um dataframe com a biblioteca pandas
# O csv utilizado e o mesmo do exercicio 1.
import pandas as pd

#importa o arquivo csv e o transforma em um DataFrame
df = pd.read_csv('exercicios/transferencias - 05_2023.csv')

#Visualiza as primeiras linhas do DataFrame com os dados do csv
print("Inicio do DATAFRAME:\n",df.head())

#Visualiza as ultimas linhas do DataFrame com os dados do csv
print("Fim do DATAFRAME:\n",df.tail())

# Apresenta um resumo dos dados da coluna ANO/MES do DataFrame
print("Resumo dos dados:\n",df.describe())

#imprime a coluna ANO/MES do dataframe
print(df['ANO / MÊS'])

#imprime somente as linhas que possuem como ValorTransferido 583145,98
print(df[df['VALOR TRANSFERIDO'] == '583145,98'])

#Cria uma nova coluna e atribui o valor 1455 a todas as linhas
df['nova coluna'] = 1455
print(df['nova coluna'])

#Retira a coluna correspondente ao ano e mes do dataframe
df.drop('ANO / MÊS', axis=1, inplace=True)
print(df.columns)

#Ordena uma coluna especifica do dataframe o que nao e tao pertintente nesse caso
df.sort_values('VALOR TRANSFERIDO', ascending=False, inplace=True)
print(df['VALOR TRANSFERIDO'])
