\n

Voc\u00ea pode usar a seguinte sintaxe para obter um valor de c\u00e9lula de um DataFrame do pandas:<\/span><\/p>\n

 #iloc method<\/span>\ndf. iloc<\/span> [0][' column_name<\/span> ']\n\n#atmethod\n<\/span>df. at<\/span> [0, ' column_name<\/span> ']\n\n#values method\n<\/span>df[' column_name<\/span> ']. values<\/span> [0]\n<\/strong><\/pre>\n
 Observe que todos os tr\u00eas m\u00e9todos retornar\u00e3o o mesmo valor.<\/span><\/p>\n
 Os exemplos a seguir mostram como usar cada um desses m\u00e9todos com o seguinte DataFrame do pandas:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' points<\/span> ': [25, 12, 15, 14, 19, 23, 25, 29],\n                   ' assists<\/span> ': [5, 7, 7, 9, 12, 9, 9, 4],\n                   ' rebounds<\/span> ': [11, 8, 10, 6, 6, 5, 9, 12]})\n\n#view DataFrame\n<\/span>df\n\n        points assists rebounds\n0 25 5 11\n1 12 7 8\n2 15 7 10\n3 14 9 6\n4 19 12 6\n5 23 9 5\n6 25 9 9\n7 29 4 12\n<\/strong><\/pre>\n
 M\u00e9todo 1: obter o valor da c\u00e9lula usando a fun\u00e7\u00e3o iloc<\/strong><\/span><\/h3>\n
 O c\u00f3digo a seguir mostra como usar a fun\u00e7\u00e3o .iloc<\/strong> para obter v\u00e1rios valores de c\u00e9lulas no DataFrame do pandas:<\/span><\/p>\n
 #get value in first row in 'points' column<\/span>\ndf. iloc<\/span> [0][' points<\/span> ']\n\n25\n\n#get value in second row in 'assists' column\n<\/span>df. iloc<\/span> [1][' assists<\/span> ']\n\n7<\/strong><\/pre>\n
 M\u00e9todo 2:<\/strong><\/span> obter o valor da c\u00e9lula usando a fun\u00e7\u00e3o at<\/strong><\/span><\/h3>\n
 O c\u00f3digo a seguir mostra como usar a fun\u00e7\u00e3o .at<\/strong> para obter diferentes valores de c\u00e9lulas no DataFrame do pandas:<\/span><\/p>\n
 #get value in first row in 'points' column\n<\/span>df. at<\/span> [0, ' points<\/span> ']\n\n25\n\n#get value in second row in 'assists' column\n<\/span>df. at<\/span> [1, ' assists<\/span> ']\n\n7<\/strong><\/pre>\n
 M\u00e9todo 3:<\/strong><\/span> obter o valor da c\u00e9lula usando a fun\u00e7\u00e3o de valores<\/strong><\/span><\/h3>\n
 O c\u00f3digo a seguir mostra como usar a fun\u00e7\u00e3o .values<\/strong> para obter v\u00e1rios valores de c\u00e9lulas no DataFrame do pandas:<\/span><\/p>\n
 #get value in first row in 'points' column\n<\/span>df[' points<\/span> ']. values<\/span> [0] \n\n25\n\n#get value in second row in 'assists' column\n<\/span>df[' assists<\/span> ']. values<\/span> [1] \n\n7<\/strong><\/pre>\n
 Observe que todos os tr\u00eas m\u00e9todos retornam os mesmos valores.<\/span><\/p>\n
