用Python在文件的列中写行 [英] Write rows in columns in file in Python

问题描述

我有一个字符串形式的句子，看起来像这样:

I have sentences,in a form of a string, that look like this :

第一句话

            hund                    
barked      4.51141770734e-07
bit         0.0673737226603
dog         0.932625826198

第二句话

            hyi                     
biid        6.12323423324e-07
bok         0.0643253
dyfs        0.514586321

，我想将它们写到这样的文件的列中:

and I want to write them into columns into a file like this :

            hund                                    hyi     
barked      4.51141770734e-07           biid        6.12323423324e-07
bit         0.0673737226603             bok         0.0643253
dog         0.932625826198              dyfs        0.514586321

而不是像这样:

            hund                    
barked      4.51141770734e-07
bit         0.0673737226603
dog         0.932625826198

            hyi                     
biid        6.12323423324e-07
bok         0.0643253
dyfs        0.514586321

有什么想法吗?

推荐答案

假设您有两个行列表，分别为lines1和lines2.如果您的字符串包含多个换行符，则可以通过调用.split('\n')来创建行列表.

Suppose you have two lists of lines, lines1 and lines2. If you have a string with multiple newlines, you can make a list of lines by calling .split('\n').

然后，您可以使用字符串格式将它们格式化为并行列:

Then, you can format them into parallel columns with string formatting:

lines = ['{:<40}{:<40}'.format(s1, s2) for s1, s2 in zip(lines1, lines2)]

示例:

a = '''            hund                    
barked      4.51141770734e-07
bit         0.0673737226603
dog         0.932625826198'''.split('\n')
b = '''            hyi                     
biid        6.12323423324e-07
bok         0.0643253
dyfs        0.514586321'''.split('\n')
lines = ['{0:<40}{1:<40}'.format(s1, s2) for s1, s2 in zip(a,b)]
print '\n'.join(lines)

输出:

            hund                                    hyi                         
barked      4.51141770734e-07           biid        6.12323423324e-07           
bit         0.0673737226603             bok         0.0643253                   
dog         0.932625826198              dyfs        0.514586321
