U kunt de volgende methoden gebruiken om de inf-<\/strong> en -inf-<\/strong> waarden te vervangen door de maximale waarde in een pandas DataFrame:<\/span><\/p>\n

Methode 1: Vervang inf door de maximale waarde in een kolom<\/strong><\/span><\/p>\n

 #find max value of column\n<\/span>max_value = np. nanmax<\/span> (df[' my_column<\/span> '][df[' my_column<\/span> '] != np. inf<\/span> ])\n\n#replace inf and -inf in column with max value of column \n<\/span>df[' my_column<\/span> ']. replace<\/span> ([np. inf<\/span> , -np. inf<\/span> ], max_value, inplace= True<\/span> )\n<\/strong><\/pre>\n
 Methode 2: Vervang inf door de maximale waarde in alle kolommen<\/strong><\/span><\/p>\n
 #find max value of entire data frame\nmax_value = np. nanmax<\/span> (df[df != np.inf<\/span> ])\n<\/span>\n#replace inf and -inf in all columns with max value\ndf. replace<\/span> ([np. inf<\/span> , -np. inf<\/span> ], max_value, inplace= True<\/span> )<\/span><\/span><\/strong><\/pre>\n
 De volgende voorbeelden laten zien hoe u deze syntaxis in de praktijk kunt gebruiken met de volgende panda’s DataFrame:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\nimport<\/span> numpy as<\/span> np\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' points<\/span> ': [18, np.inf, 19, np.inf, 14, 11, 20, 28],\n                   ' assists<\/span> ': [5, 7, 7, 9, 12, 9, 9, np.inf],\n                   ' rebounds<\/span> ': [np.inf, 8, 10, 6, 6, -np.inf, 9, 12]})\n\n#view DataFrame\n<\/span>print<\/span> (df)\n\n   points assists rebounds\n0 18.0 5.0 lower\n1 lower 7.0 8.0\n2 19.0 7.0 10.0\n3 lower 9.0 6.0\n4 14.0 12.0 6.0\n5 11.0 9.0 -inf\n6 20.0 9.0 9.0\n7 28.0 lower 12.0\n<\/strong><\/span><\/pre>\n
 Voorbeeld 1: Vervang inf door de maximale waarde in een kolom<\/strong><\/span><\/h2>\n
 De volgende code laat zien hoe u de inf-<\/strong> en -inf-<\/strong> waarden in de bounces-kolom vervangt door de maximale waarde in de bounces-kolom:<\/span><\/p>\n
 #find max value of rebounds\n<\/span>max_value = np. nanmax<\/span> (df[' rebounds<\/span> '][df[' rebounds<\/span> '] != np. inf<\/span> ])\n\n#replace inf and -inf in rebounds with max value of rebounds\n<\/span>df[' rebounds<\/span> ']. replace<\/span> ([np. inf<\/span> , -np. inf<\/span> ], max_value, inplace= True<\/span> )\n\n#view updated DataFrame\n<\/span>print<\/span> (df)\n\n   points assists rebounds\n0 18.0 5.0 12.0\n1 lower 7.0 8.0\n2 19.0 7.0 10.0\n3 lower 9.0 6.0\n4 14.0 12.0 6.0\n5 11.0 9.0 12.0\n6 20.0 9.0 9.0\n7 28.0 lower 12.0<\/strong><\/span><\/pre>\n
 Houd er rekening mee dat elke inf-<\/strong> en -inf-<\/strong> waarde in de bouncekolom is vervangen door de maximale waarde in die kolom van 12<\/strong> .<\/span><\/p>\n
 Voorbeeld 2: Vervang inf door de maximale waarde in alle kolommen<\/strong><\/span><\/h2>\n
 De volgende code laat zien hoe u de inf-<\/strong> en -inf-<\/strong> waarden van elke kolom vervangt door de maximale waarde van het gehele dataframe:<\/span><\/p>\n
 #find max value of entire data frame\nmax_value = np. nanmax<\/span> (df[df != np.inf<\/span> ])\n\n#replace all inf and -inf with max value\n<\/span>df. replace<\/span> ([np. inf<\/span> , -np. inf<\/span> ], max_value, inplace= True<\/span> )\n\n#view updated DataFrame\n<\/span>print<\/span> (df)\n\n   points assists rebounds\n0 18.0 5.0 28.0\n1 28.0 7.0 8.0\n2 19.0 7.0 10.0\n3 28.0 9.0 6.0\n4 14.0 12.0 6.0\n5 11.0 9.0 28.0\n6 20.0 9.0 9.0\n7 28.0 28.0 12.0\n<\/span><\/span><\/strong><\/span><\/pre>\n
 Merk op dat elke inf-<\/strong> en -inf-<\/strong> waarde in elke kolom is vervangen door de maximale waarde in het gehele dataframe van 28<\/strong> .<\/span><\/p>\n
