python 字符串居中

下面的代碼可以讓字符串居中，左對齊和右對齊，字符串長度設置為50，居中后左右補充空格，右對齊會在左側補充空格

 

string1 = "Now I am here."
print( string1.center(50))
print( string1.rjust(50))
print (string1.ljust(50))

result:

                  Now I am here.                  
                                    Now I am here.
Now I am here.
