We can observe that the values of column 'One' is an int, we need to convert this data type into string or object.For this purpose we will use pandas.DataFrame.astype() and pass the data type inside the function.Let us understand with the help of an example,...

Use ‘ignore’ to not raise exceptions (suppress errors/exceptions). On error return the original object. Return value of astype() It returns a Series with the changed data type. To run some examples of converting a string column to an integer column, let’s create Pandas DataFrame using da...
We can pass the ndarrays object to the DataFrame() constructor and set the column values to create a DataFrame with a heterogeneous data value. Here is an example of a DataFrame with heterogeneous data. import numpy as np import pandas as pd ...
As you can see, the first column x1 has the object dtype (note that pandas stores strings as objects). This shows that we have converted the boolean data type of our input data set to a character string object. Example 2: Replace Boolean by String in Column of pandas DataFrame ...

The JSON consists of an object with keys that are string representations of arrays. The keys represent a combination of customer IDs and months. The corresponding values are objects containing keys such as “DataUsage” and “MinutesUsage”. ...
Convert an Object-Type Column to Float in Pandas An object-type column contains a string or a mix of other types, whereas a float contains decimal values. We will work on the following DataFrame in this article. importpandasaspd df=pd.DataFrame([["10.0",6,7,8],["1.0",9,12,14],["...
