display.float_format None The callable should accept a floating point number and return a string with the desired format of the number. This is used in some places like SeriesFormatter. See core.format.EngFormatter for an example. display.large_repr truncate For DataFrames exceeding max_rows/ma...
In the above program, we first import pandas library as pd and then we create a dictionary where we assign floating point values to the month and salary. Then we use the format function to move three places after the decimal point and then the program is executed and the output is as sh...
