字符串在輸出

格式化我有一個Python腳本，看起來像這樣：字符串在輸出

print "Header 1" 
    print "\t Sub-header 1" 
    print "\t\t (*) Sentence 1 begins here and goes on... and ends here."

的句子被印刷在與同類格式的環路，它給終端這樣的輸出：

Header 1 
    Sub-header 1 
     (*) Sentence 1 begins here and goes on... 
and ends here. 
     (*) Sentence 2 begins here and goes on ... 
and ends here. 
     . 
     . 
     .

有什麼辦法可以使格式如下？：

Header 1 
    Sub-header 1 
     (*) Sentence 1 begins here and goes on... 
      and ends here. 
     (*) Sentence 2 begins here and goes on ... 
      and ends here. 
     . 
     . 
     .

我使用print'print'（'Text_1 =％-20s | Text_2 =％0s | Text_3 =％6s \ n'）％（'Here'，'Here_2'，'Here_3'）'在屏幕上打印。這對你有幫助嗎？（運行它） – SnuKies

確實有一種方法可以根據需要進行格式設置，但正確的方法可能取決於您現有的代碼。你能解釋一下這個格式是如何完成的嗎？ – Tryph

@SnuKies：謝謝，但對我的情況沒有幫助。由於句子太長，格式仍然在終端中斷。 –

與textwrap模塊的幫助下，它可以很容易實現：

import textwrap 

LINE_LENGTH = 80 
TAB_LENGTH = 8 


def indent(text, indent="\t", level=0): 
    return "{}{}".format(indent * level, text) 

def indent_sentence(text, indent="\t", level=0, sentence_mark=" (*) "): 
    indent_length = len(indent) if indent != "\t" else TAB_LENGTH 
    wrapped = textwrap.wrap(text, 
          LINE_LENGTH 
          - indent_length * level 
          - len(sentence_mark)) 
    sentence_new_line = "\n{}{}".format(indent * level, " " * len(sentence_mark)) 
    return "{}{}{}".format(indent * level, 
          sentence_mark, 
          sentence_new_line.join(wrapped)) 


print indent("Header 1") 
print indent("Sub-header 1", level=1) 
print indent_sentence("Sentence 1 begins here and goes on... This is a very " 
         "long line that we will wrap because it is nicer to not " 
         "have to scroll horizontally. and ends here.", 
         level=2)

它打印這個在Windows控制檯，選項卡是8個字符長：

Header 1 
     Sub-header 1 
       (*) Sentence 1 begins here and goes on... This is a very long 
        line that we will wrap because it is nicer to not have to 
        scroll horizontally. and ends here.
