Accepted answer. You can convert most of the columns by just calling convert_objects: In [36]: df = df.convert_objects (convert_numeric=True) df.dtypes Out [36]: Date object WD int64 Manpower float64 2nd object CTR object 2ndU float64 T1 int64 T2 int64 T3 int64 T4 float64 dtype: object. For column '2nd' and 'CTR' we can call the vectorised str. . Yes, actually when you use Python's native float to specify the dtype for an array , numpy converts it to float64. As given in documentation -. Note that, above, we use the Python float object as a dtype. NumPy knows that int refers to np.int_, bool means np.bool_ , that float is np.float_ and complex is np.complex_. data_new4 = data. copy() # Create copy of DataFrame data_new4 ['x1'] = data_new4 ['x1']. apply(str) # Transform integer to string. Now, let's return the data types of all columns in our data: print( data_new4. dtypes) # Check data types of columns # x1 object # x2 int64 # x3 int64 # dtype: object. As you can see, we have converted only the. Method 3: Use of numpy.asarray with the dtype. The third method for converting elements from float to int is np.asarray (). Here you have pass your float array with the dtype="int" as an arguments inside the function. You will get the same output as the above methods. Just run the given lines of code. 2 days ago · How to Solve Python ValueError: Can only compare identically-labeled DataFrame objects; How to Solve Python ValueError: cannot set a row with mismatched columns; To learn more about Python for data science and machine learning, go to the online courses page on Python for the most comprehensive courses available.
