Pandas Convert Float to int (Integer) Use pandasDataFrame.astype()function to convert float to int (integer), you can apply this on a specific column. Below example convertsFeecolumn toint32fromfloat64. You can also usenumpy.dtypeas a param to this method. ...
You can useDataFrame.astype(int)orDataFrame.apply()method to convert a column to int (float/string to integer/int64/int32 dtype) data type. If you are converting float, you would know float is bigger than int type, and converting into int would lose any value after the decimal. Advertisem...
Method 2 : Convert float type column to int using astype() method with dictionary Here we are going to convert the float type column in DataFrame to integer type usingastype()method. we just need to pass int keyword inside this method throughdictionary. Syntax: dataframe['column'].astype({"...
Convert Pandas DataFrame Column tointWith Rounding Off We can round off thefloatvalue tointby usingdf.round(0).astype(int). importpandasaspdimportnumpyasnp df=pd.DataFrame(np.random.rand(5,5)*5)print("*** Random Float DataFrame ***")print(df)print("***")print("***")print("*** ...
# of 'Weight' column print(df.dtypes) 输出: 让我们将重量类型转换为浮点数 Python3实现 # Now we will convert it from 'int' to 'float' type # using DataFrame.astype() function df['Weight']=df['Weight'].astype(float) print()
Theto_numeric()method will convert the values in theDataFrameto int or float, depending on the supplied values. main.py importpandasaspd df=pd.DataFrame({'id':['1','2','3','4'],'experience':['1','1','5','7'],'salary':['175.1','180.2','190.3','205.4'],})print(df.dtypes...

Example 1: Convert Single pandas DataFrame Column from Integer to Float This example explains how to convert one single column from the integer data type tofloat. To accomplish this task, we can apply the astype function as you can see in the following Python code: ...
# import pandas libraryimportpandasaspd# dictionaryData = {'Name':['GeeksForGeeks','Python'],'Unique ID':['900','450']}# create a dataframe objectdf = pd.DataFrame(Data)# convert string to an integerdf['Unique ID'] = df['Unique ID'].astype(int)# show the dataframeprint(df) ...
#Now we will convert it from'int'to'float'type#using DataFrame.astype()functiondf['Weight'] = df['Weight'].astype(float) print()#lets find out the datatypeafter changingprint(df.dtypes)#printdataframe.df 输出: 在上面的示例中,我们将“重量”列的数据类型从 ‘int64’ 更改为 ‘float64’。
