python - 分割字符串以进行打印

Question

我需要在一些字符串周围打印一些标题，你可以看到它在这里工作正常，尽管如果字符串真的很长，我需要将其拆分，然后打印更长的标题。

看起来不错，尽管 SSM 测试，我想分割一定数量的字符，也许 100 个，或者只是在套件之间的空白处。

我真的不太确定如何做到这一点，这是当前执行此操作的代码。

#calculate lengths to make sure header is correct length
        l1 = len(x)
        l2 = len(y)
        skip = False
        if 'disable=' in test and 'disable="*"' not in test:
            skip = True
        #if entire test suite is to be disabled or not run
        if disable:
            headerBreak ="+" + "="*(l1+12) + "+"
            print headerBreak
            print "| Skipping: %s |" % x
        #if the test suite will be executed
        else:
            if skip == False:
                l2 = 0
            headerBreak =  "+" + "="*(max(l1,l2)+11) + "+"
            print headerBreak
            print "| Running: %s" % x, ' '*(l2-l1)+ '|'
            #if some suites are disabled but some are still running
            if skip:
               print "| Skipping:%s |" % y
        print headerBreak
        sys.stdout.flush()

您可以使用textwrap模块来简化这个

例如，如果最大宽度为 44

>>> max_width = 44
>>> header='''Skipping:"Secondary Subset Manager Tests"/"SSSM_3 Multi Sequence" "Secondary Subset Manager Tests"/"SSSM_2 Steady State" "Secondary Subset Manager Tests"/"SSSM_4 Test Abort" "Secondary Subset Manager Tests"/"SSSM_6 Test extend" "Secondary Subset Manager Tests"/"SSSM_9 exceptions" "Secondary Subset Manager Tests"/"SSSM_11 failed io"'''
>>> h = ["Running: ssm"] + textwrap.wrap(header, width=max_width-4)
>>> maxh = len(max(h, key=len))
>>> print "+="  + "="*maxh + "=+"
+==========================================+
>>> for i in h:
...     print "| " + i.ljust(maxh) + " |"... 
| Running: ssm                             |
| Skipping:"Secondary Subset Manager       |
| Tests"/"SSSM_3 Multi Sequence"           |
| "Secondary Subset Manager Tests"/"SSSM_2 |
| Steady State" "Secondary Subset Manager  |
| Tests"/"SSSM_4 Test Abort" "Secondary    |
| Subset Manager Tests"/"SSSM_6 Test       |
| extend" "Secondary Subset Manager        |
| Tests"/"SSSM_9 exceptions" "Secondary    |
| Subset Manager Tests"/"SSSM_11 failed    |
| io"                                      |
>>> print "+="  + "="*maxh + "=+"
