String Operations in Pandas

Text data needs cleaning - fixing case, removing whitespace, extracting parts. Pandas provides string methods through .str.

Convert case:

df['name'].str.lower()
df['name'].str.upper()
df['name'].str.title()

Strip whitespace:

df['email'].str.strip()

Check for substrings:

df['email'].str.contains('gmail')

Replace text:

df['phone'].str.replace('-', '')

All standard Python string methods are available through .str, applied element-wise to the entire column.

I cover text processing in my Pandas course.
