Pandas – An open-source library which is used by any programmer. It is a useful library that is used for analyzing the data and for manipulating the data. It is fast, flexible, and understandable, handles the missing data easily. Not only it provides but also enhances the performance of data manipulation and analysis tools with the powerful data structure.
There are four ways of converting integers to strings in pandas.
Method 1: map(str)
frame[‘DataFrame Column’]= frame[‘DataFrame Column’].map(str)
Method 2: apply(str)
frame[‘DataFrame Column’]= frame[‘DataFrame Column’].apply(str)
Method 3: astype(str)
frame[‘DataFrame Column’]= frame[‘DataFrame Column’].astype(str)
Method 4: values.astype(str)
frame[‘DataFrame Column’]= frame[‘DataFrame Column’].values.astype(str)
In order to find out the fastest method we find the time taken by each method required for converting integers to the string. The method which requires the minimum time for conversion is considered to be the fastest method.
