python - 如何重新组织列中的输出结果

Question

我的代码正在从一个文本文件中读取，该文件包含以逗号分隔的数字列表。如果存在空格和/或制表符，它将检测到它。我的代码运行良好，但现在我想让它看起来更有条理，并且更好地读取它写入的输出文件。

代码:

import os
from zipfile import ZipFile
def pain():

    print("\t\t\tinput_files.zip has been unzipped")
    with ZipFile('input_files.zip', 'r') as zipObj:
        zipObj.extractall()
        listOfFileNames = zipObj.namelist()
        for fileName in listOfFileNames:
            if fileName.endswith('.txt'):
                zipObj.extract(fileName, 'storage')


    outfile = "output2.txt"                 #this will be the filename that the code will write to 
    baconFile = open(outfile,"wt")
    file_name1 = "file.txt"
    print('Filename\tLine\tnumber of numbers\tstring separated by a comma\twhite space found\ttab found\tcarriage return found\n')         #This prints the master column in the python shell and this is the way the code should collect the data 
    baconFile.write('Filename\tLine\tnumber of numbers\tstring separated by a comma\twhite space found\ttab found\tcarriage return found\n') #This prints the master column in the output file and this is the way the code should collect the data

    #for filename in os.listdir(os.getcwd() + "/input_files"):
    for filename in os.listdir('C:\Users\M29858\Desktop\TestPy\Version10\input_files'):
        with open("input_files/" + filename, 'r') as f:
            if file_name1 in filename:

                output_contents(filename, f, baconFile)
    baconFile.close()       #closes the for loop that the code is writing to


def output_contents(filename, f, baconFile):     #using open() function to open the file inside the directory
    index = 0
    for line in f:
                                        #create a list of all of the numerical values in our line
        content = line.split(',')       #this will be used to count the amount numbers before and after comma
        whitespace_found = False
        tab_found = False
        false_string = "False (end of file)"
        carriage_found = false_string 
        sigfigs = ""

        index += 1                            #adds 1 for every line if it finds what the command wants

        if " " in line:                         #checking for whitespace
            whitespace_found = True
        if "\t" in line:                        #checking for tabs return
            tab_found = True
        if '\n' in line:                    #checking if there is a newline after the end of each line
            carriage_found = True                                        
        sigfigs = (','.join(str(len(g)) for g in re.findall(r'\d+\.?(\d+)?', line )))    #counts the sigsfigs after decimal point 

        print(filename + "\t{0:<4}\t{1:<17}\t{2:<27}\t{3:17}\t{4:9}\t{5:21}"
              .format(index, len(content), sigfigs, str(whitespace_found), str(tab_found), str(carriage_found)))   #whatever is inside the .format() is the way it the data is stored into
        baconFile.write('\n')
        baconFile.write( filename + "\t{0:<4}\t{1:<17}\t{2:<27}\t{3:17}\t{4:9}\t{5:21}"
                        .format(index, len(content), sigfigs, str(whitespace_found), str(tab_found), str(carriage_found)))



if __name__ == '__main__':
    pain()```


My filename text file:
```none
1.0,    1.023, 1.45
1.0,1.023,1.45
1

主列:文件名(制表符)行(制表符)数字数量(制表符)由逗号(制表符)分隔的“sigfigs”字符串(制表符)空格(制表符)制表符(制表符)找到回车符

预期输出文件:

expected:
```none
Filename    Line    number of numbers    string of “sigfigs/decimal Places” separated by a comma    white space found    tab found    carriage return found    
filename    1            3                       1,3,2                                                    TRUE              FALSE               TRUE        
filename    2            3                       1,3,2                                                    TRUE              FALSE               TRUE
filename    3            1                       1                                                        FALSE             FALSE               FALSE

实际:

Line 1:   1 3   2 tab detected,  White Space Detected, 
Line 2:   1 3   2 No Error
Line 3:   0 Missing carriage return,  No Error
Numbers in Line 1: 3
Numbers in Line 2: 3
Numbers in Line 3: 1
Number of lines: 3

您只需将所有值保存在表中即可。处理完文件后，只需迭代一个循环即可创建 formatted String您将把它保存在您的文件中。

要将值居中，只需使用符号 ^ 后跟列之间的空格即可。下面我制作了一个类似的所需输出的示例:

tabled = [
    ['Filename', 'Line', 'number of numbers', 'string separated by a comma', 'white space found', 'tab found', 'carriage return found'],
    ['filename', '1', '3', '1, 3, 2', 'TRUE', 'FALSE', 'TRUE'], 
    ['filename', '2', '3', '1, 3, 2', 'TRUE', 'FALSE', 'TRUE'],
    ['filename', '3', '1', '1', 'FALSE', 'FALSE', 'TRUE']
]

for row in tabled:
    print("{: ^30} {: ^30} {: ^30} {: ^30} {: ^30} {: ^30} {: ^30}".format(*row))

这给出了输出:

   Filename                         Line                    number of numbers         string separated by a comma         white space found                  tab found                carriage return found     
   filename                          1                              3                           1, 3, 2                          TRUE                          FALSE                           TRUE             
   filename                          2                              3                           1, 3, 2                          TRUE                          FALSE                           TRUE             
   filename                          3                              1                              1                            FALSE                          FALSE                           TRUE
