In NumPy, you can use functions like np.round(), np.ceil(), np.floor(), and np.trunc() to apply different rounding strategies. For pandas, the df.round() method allows rounding of entire DataFrames or specific columns.By the end of this tutorial, you’ll understand that:Python uses ...
Fillna: how to deal with missing values in Python At a high level, the Pandas fillna method really does one thing: it replaces missing values in Pandas. There are actually a few different ways that missing values can be coded in Python. Generally, in Python, there is the valueNone. Addi...
