dataframe without append how to use function to achieve it

To create a dataframe without using the append method, you can use the pandas.DataFrame function and pass in a dictionary of your data.

For example:

import pandas as pd

data = {'name': ['Alice', 'Bob', 'Charlie'],
        'age': [25, 30, 35],
        'city': ['New York', 'San Francisco', 'Los Angeles']}

df = pd.DataFrame(data)
print(df)

Output:

       name  age           city
0     Alice   25       New York
1       Bob   30  San Francisco
2  Charlie   35    Los Angeles

You can also create a function that returns a dataframe based on some input parameters. For example:

def create_dataframe(names, ages, cities):
    data = {'name': names,
            'age': ages,
            'city': cities}
    return pd.DataFrame(data)

df = create_dataframe(['Alice', 'Bob', 'Charlie'], [25, 30, 35], ['New York', 'San Francisco', 'Los Angeles'])
print(df)

Output:

       name  age           city
0     Alice   25       New York
1       Bob   30  San Francisco
2  Charlie   35    Los Angeles
