you can simply use thetype() methodby providing the variable name, Thetype()method is a built-in method that determines and returns the type of the given parameter. Based on the return value (class) you can determine whether the given variable is a list, NumPy array, o...
Check if the first value in the array is equal to every other value. If the condition is met, all values in the column are equal. main.py import pandas as pd df = pd.DataFrame({ 'name': ['Alice', 'Bobby', 'Carl', 'Dan'], 'experience': [3, 3, 3, 3], 'salary': [175.1...
These methods evaluate each object in the Series or DataFrame and provide a boolean value indicating if the data is missing or not. For example, let’s create a simple Series in pandas: import pandas as pd import numpy as np s = pd.Series([2,3,np.nan,7,"The Hobbit"]) Now ...
