# Pandas: Create a Tuple from two DataFrame Columns using apply() You can also use the DataFrame.apply() method to create a tuple from two DataFrame columns. main.py import pandas as pd df = pd.DataFrame({ 'first_name': ['Alice', 'Bobby', 'Carl'], 'salary': [175.1, 180.2, 190....
In Python Pandas, the MultiIndex object is the hierarchical analogue of the standard Index object which typically stores the axis labels in pandas objects. You can consider that MultiIndex is an array of unique tuples. Thepandas.MultiIndex.from_arrays()method is us...
The above code creates a pandas DataFrame object named ‘df’ with three columns X, Y, and Z and five rows. The values for each column are provided in a dictionary with keys X, Y, and Z. The print(df) statement prints the entire DataFrame to the console. For more Practice: Solve th...
import pandas as pd myDf=pd.DataFrame(columns=["A", "B", "C"]) print(myDf) Output: Empty DataFrame Columns: [A, B, C] Index: [] Here, we have created a dataframe with columns A, B, and C without any data in the rows. ...
Similarly, thereset_index()method in pandas is commonly used to reset the index of a DataFrame, moving it into a column, and then creating a new default integer index. # Change the index to a column & create new index df = df.reset_index() print(df) # Output: # index Courses Cours...

To handle missing or malformed data, you can use pandas’ built-in functions: df = df.dropna() # Convert data types if necessary df = df.astype({'X': float, 'Y': float, 'Z': float}) # Extract specific columns for 3D plotting ...
This exercise demonstrates how to create a pair plot using Seaborn to visualize relationships between all numerical columns in a DataFrame.Sample Solution :Code :import pandas as pd import seaborn as sns import matplotlib.pyplot as plt # Create a sample DataFrame df = pd.DataFrame(...
