The "dtype" (data type) of "int64" in this instance indicates that the Series comprises integers. 0 1000 1 2000 2 3000 3 4000 4 5000 dtype: int64 Explanation The Pandas library is imported in the first line and, for simplicity, renamed to "pd." A Python list with some data is ...
Pandas provides thestr.lower()method to convert string values to lowercase within a DataFrame column. Apply thestr.lower()method to the desired column directly, or via theapply()function. Ensure the column data type is compatible with string operations before applyingstr.lower(). ...
Given a Pandas DataFrame, we have to create a categorical type of column.ByPranit SharmaLast updated : September 26, 2023 Pandas is a special tool that allows us to perform complex manipulations of data effectively and efficiently. Inside pandas, we mostly deal with a dataset in the form of...
Yes, you can specify the exact integer data type when usingastype(). For example,df['column_name'].astype('int32')will convert to int32. How can I convert multiple columns to integers in a Pandas DataFrame? To convert multiple columns to integers, you can apply the conversion methods to...
Pandas is used to read data One of the column was misread as number (int) instead of string/category (str) That column is manually typecast with the help of astype function [astype('str') / astype('category')] Pandas-Profiling is used to generate report The new type of the column is...

import pandas as pd import seaborn as sns import matplotlib.pyplot as plt df = pd.read_csv("./pokemon_data.csv") 首先我们观察一下数据的尺寸,可以通过 df.shape 这个来实现。当然 df.info() 能够给我们更加详细的每个列的信息。这里我们通过这个方式,可以发现这个数据集一共收录了801行,41列的数据。
