python 字符串居中

下面的代碼可讓字符串居中，左對齊和右對齊，字符串長度設置爲50，居中後左右補充空格，右對齊會在左側補充空格

 

1 string1 = "Now I am here."
2 print( string1.center(50))
3 print( string1.rjust(50))
4 print (string1.ljust(50))

result:

1                   Now I am here.                  
2                                     Now I am here.
3 Now I am here.
