Python right alignment example method

For example, there is a dictionary as follows:

 dic ={"name":"botoo","url":"//www.zalou.cn","page":"88","isNonProfit":"true","address":"china",}

The desired output is as follows:

name:botoo
url:https:www.zalou.cn
page:88
isNonProfit:ture
address:china

First get the maximum value of the dictionary max(map(len, dic.keys()))

Then use

Str.rjust() align right

or

Str.ljust() left justify

or

Str.center() The center method has sequential output.

 dic ={"name":"botoo","url":"//www.zalou.cn","page":"88","isNonProfit":"true","address":"china",}
    
 d =max(map(len, dic.keys())) #Get the maximum value of key
    
 for k in dic:print(k.ljust(d),":",dic[k])
   
name    : botoo
url     ://www.zalou.cn
page    :88
isNonProfit :true
address   : china
 for k in dic:print(k.rjust(d),":",dic[k])
   
 name : botoo
 url ://www.zalou.cn
 page :88
isNonProfit :true
 address : china
 for k in dic:print(k.center(d),":",dic[k])
   
 name  : botoo
 url   ://www.zalou.cn
 page  :88
isNonProfit :true
 address  : china

The usage of str.ljust() is like this;

 s ="adc"
 s.ljust(20,"+")'adc+++++++++++++++++'
 s.rjust(20)'adc'
 s.center(20,"+")'++++++++adc+++++++++'

Knowledge point expansion:

Alignment of strings in python

ljust(), rjust() and center() functions represent left, right, and center alignment, respectively

str.ljust(width[, fillchar]): left justify, width — specify the length of the string, fillchar — fill character, the default is a space;
str.rjust(width[, fillchar]): right justify, width — specify the length of the string, fillchar — fill character, the default is a space;
str.center(width[, fillchar]): center alignment, width — the total width of the string, fillchar — the filling character, the default is a space.

test ='hello world'print(test.ljust(20))print(test.ljust(20,'*'))print(test.rjust(20,'*'))print(test.center(20,'*'))print(test.center(20))
 
# The output results are as follows:
hello world******************hello world
****hello world*****
 hello world
