Note that in above example, the DataFrame is created empty first, and then columns are added one by one using the assignment operator (=).
Creating an empty Pandas DataFrame, and then filling it in Python

df['name'] = ['John', 'Jane', 'Bob']
df['age'] = [30, 25, 35]
df['city'] = ['New York', 'Los Angeles', 'Chicago']
