让我们讨论如何在 Pandas 中向现有 DataFrame 添加新列。我们可以通过多种方式完成这项任务。
方法 #1：通过将新列表声明为列。
# Import pandas package
import pandas as pd
# Define a dictionary containing Students data
data = {'Name': ['Jai', 'Princi', 'Gaurav', 'Anuj'],
'Height': [5.1, 6.2, 5.1, 5.2],
'Qualification': ['Msc', 'MA', 'Msc', 'Msc']}
# Convert the dictionary into DataFrame
df = pd.DataFrame(data)
# Declare a list that is to be converted into a column
address = ['Delhi', 'Bangalore', 'Chennai', 'Patna']
# Using 'Address' as the column name
# and equating it to the list
df['Address'] = address
# Observe the result
print(df)
方法 2：通过使用DataFrame.insert()
它提供了在我们喜欢的任何位置添加列
