Pandas dataframe query single quotes in a string argument

Question

How can I escape the single quotes character in the string I want to search for?

Example:

strng = "King's palace"
df.query("fieldname == %s" %(strng))

This query is not returning data because of the quotes. Escaping is not helping.

Answer 1

Use this solution:

# Test data
df = pd.DataFrame({'fieldname': ['King's palace', 'Hilton']})

strng = "King's palace"
df.query("fieldname == @strng")

Output:

       fieldname
0  King's palace

I tried giving this as df.query(r'fieldname == %s' %(strng)).
It worked.
