Not all the arguments converted during string formatting-CodePudding

Df1=pd. DataFrame (np) random) randn (5, 5), the columns=list (" abcde "))
Df1. Applymap (lambda x: '2' f % x)
Want to format the generated random Numbers, only to get this error, how to return a responsibility

CodePudding user response:

The format string, lack the %
The changed code is as follows:

 import numpy as np 
Df1=pd. DataFrame (np) random) randn (5, 5), the columns=list (" abcde ")) 
Print (df1) 
Df1=df1. Applymap (lambda x: x % %. 2 f) 
Print (df1)
