Da Type Conversion in Data Analytics

Convert data types with pd.to_numeric(), pd.to_datetime(), astype().

pd.to_numeric() with errors='coerce' converts invalid values to NaN.

astype() for simple conversions: df['col'].astype('int'), .astype('float'), .astype('str')

Categorical type reduces memory usage for repeated values.

Check data types with df.dtypes or df.info().

Da Type Conversion — Syntax

# Basic conversion: df['col'].astype('int')
# Safe numeric: pd.to_numeric(df['col'], errors='coerce')
# To datetime: pd.to_datetime(df['col'], format='%Y-%m-%d')
# To category: df['col'].astype('category')
