id object name object cost int64 quantity object dtype: object Method 4 : Convert string/object type column to int using astype() method Here we are going to convert the string type column in DataFrame to integer type using astype() method. we just need to pass int keyword inside this met...
So I found a workaround for what I want. Allow Pandas to change to int64 when no decimals are present. InStep 6(inthe original post), instead of doingnewdf.convert_dtypes(), to force a simpler dtype you can donewdf.astype('object').convert_dtypes(), it's one more step than I wou...
# Using pandas.to_numeric()df['Fee']=pd.to_numeric(df['Fee'])print(df.dtypes)# Output:# Courses object# Fee int64# Duration object# Discount object# dtype: object If you don’t want to lose the values with letters in them, usestr.replace()with a regex pattern to drop the non-di...

pandas does not have any support for NumPy string dtype yet, so these are treated purely as Python objects. That is why without conversion, pandas results in object dtype. df_with_numpy_values = pd.DataFrame( { "col_int": [np.int64(1), np.int64(2)], "col_float": [np.float64(...
Duration object Discount int32 dtype: object Using apply(np.int64) to Cast to Integer You can also useDataFrame.apply()method to convertFeecolumn from string to integer in pandas. As you see in this example we are usingnumpy.int64. Before going to use numpy functions we need to import num...
