\n

Voc\u00ea pode usar os seguintes m\u00e9todos para adicionar e subtrair meses de uma data no pandas:<\/span><\/p>\n

M\u00e9todo 1: adicionar meses at\u00e9 a data<\/strong><\/span><\/p>\n

 from<\/span> pandas. tseries<\/span> . offsets<\/span> import<\/span> DateOffset\n<\/span>\ndf[' date_column<\/span> '] + DateOffset(months= 3<\/span> )\n<\/span><\/span><\/strong><\/pre>\n
 M\u00e9todo 2: subtraia os meses da data<\/strong><\/span><\/p>\n
 from<\/span> pandas. tseries<\/span> . offsets<\/span> import<\/span> DateOffset\n<\/span>\ndf[' date_column<\/span> '] - DateOffset(months= 3<\/span> )<\/span><\/span><\/strong><\/pre>\n
 Os exemplos a seguir mostram como usar cada m\u00e9todo na pr\u00e1tica com o seguinte DataFrame do pandas:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' date<\/span> ': pd. date_range<\/span> (start='1\/5\/2022', freq='M', periods= 10<\/span> ),\n                   ' sales<\/span> ': [6, 8, 9, 5, 4, 8, 8, 3, 5, 9]})\n\n#view DataFrame\n<\/span>print<\/span> (df)\n\n        dirty dates\n0 2022-01-31 6\n1 2022-02-28 8\n2 2022-03-31 9\n3 2022-04-30 5\n4 2022-05-31 4\n5 2022-06-30 8\n6 2022-07-31 8\n7 2022-08-31 3\n8 2022-09-30 5\n9 2022-10-31 9\n<\/strong><\/span><\/pre>\n
 Exemplo 1: Adicione meses at\u00e9 a data no Pandas<\/strong><\/span><\/h2>\n
 O c\u00f3digo a seguir mostra como criar uma nova coluna que adiciona 3 meses ao valor da coluna de data<\/strong> :<\/span><\/p>\n
 from<\/span> pandas. tseries<\/span> . offsets<\/span> import<\/span> DateOffset\n\n#create new column that adds 3 months to date\n<\/span>df[' date_plus3<\/span> '] = df. date<\/span> + DateOffset(months= 3<\/span> )\n\n#view updated DataFrame\n<\/span>print<\/span> (df)\n\n        date sales date_plus3\n0 2022-01-31 6 2022-04-30\n1 2022-02-28 8 2022-05-28\n2 2022-03-31 9 2022-06-30\n3 2022-04-30 5 2022-07-30\n4 2022-05-31 4 2022-08-31\n5 2022-06-30 8 2022-09-30\n6 2022-07-31 8 2022-10-31\n7 2022-08-31 3 2022-11-30\n8 2022-09-30 5 2022-12-30\n9 2022-10-31 9 2023-01-31<\/span><\/span><\/strong><\/pre>\n
 A nova coluna date_plus3<\/strong> representa valores da coluna de data<\/strong> com tr\u00eas meses anexados a cada valor.<\/span><\/p>\n
 Exemplo 2: subtraia meses da data no Pandas<\/strong><\/span><\/h2>\n
 O c\u00f3digo a seguir mostra como criar uma nova coluna que subtrai 3 meses do valor da coluna de data<\/strong> :<\/span><\/p>\n
 from<\/span> pandas. tseries<\/span> . offsets<\/span> import<\/span> DateOffset\n\n#create new column that subtracts 3 months from date\n<\/span>df[' date_minus3<\/span> '] = df. date<\/span> + DateOffset(months= 3<\/span> )\n\n#view updated DataFrame\n<\/span>print<\/span> (df)\n\n        date sales date_minus3\n0 2022-01-31 6 2021-10-31\n1 2022-02-28 8 2021-11-28\n2 2022-03-31 9 2021-12-31\n3 2022-04-30 5 2022-01-30\n4 2022-05-31 4 2022-02-28\n5 2022-06-30 8 2022-03-30\n6 2022-07-31 8 2022-04-30\n7 2022-08-31 3 2022-05-31\n8 2022-09-30 5 2022-06-30\n9 2022-10-31 9 2022-07-31<\/span><\/span><\/strong><\/pre>\n
 A nova coluna date_minus3<\/strong> representa os valores da coluna de data<\/strong> com tr\u00eas meses subtra\u00eddos de cada valor.<\/span><\/p>\n
