Overview:
- “Less Than” is a comparison operation. For pandas Series objects, the “Less Than“ operation is implemented through the “<” operator as well as the function Series.lt();
- When using the function lt(), Python developers has an option to provide replacement for any occurrence of None/NaN/missing values.
Example:
The Python example below compares two pandas series objects of string literals and prints the resulting series on to the console.

# Example Python program to compare pandas series instance # using lt() function i.e., applying less than < condition
import pandas as pds
# Define strings token1 = "axybd"; token2 = "gbuio";
# Load the strings into lists making one character string literals tokenList1 = list(token1); tokenList2 = list(token2);
# Load the lists of characters into series objects series1 = pds.Series(tokenList1); series2 = pds.Series(tokenList2);
# Compare string literals of series1 with series2 series3 = series1.lt(series2);
print("pandas Series of strings 1:"); print(series1);
print("pandas Series of strings 2:"); print(series2);
print("pandas Series of strings 1 < pandas Series of strings 2"); print(series3); |
Output:
