需要修复熊猫数据框的输出

Question

The program works great but the output is just not in the format i want. As you can se from the output below, the printout for the 'from' and 'to' data is not at the same level as the printout for 'route' and 'date'. How can this be fixed? I want the output from date,route,from and to on the same level.

      date    route
  0  05/15/2014  C000001     from     to
  0  278.7  278.6
      date    route
  0  05/15/2014  C000001     from     to
  0  278.6  278.5

Also, this program is supposed to iterate through any number of .txt files. But it only works when there is just one text file in the target directory.

def array_setter():
    import os
    import glob
    import numpy as np
    import pandas as pd
    os.chdir\
    ('/Users/thomaswolff/Documents/Data Exports')
    for file in glob.glob('*.TXT'):
        reader = open(file)
        headerLine = reader.readline()
        mainBody = reader.readlines()
        for col in mainBody:
            valueList = col.split(",")
            data = np.array([valueList])

            arrstr = data[:,[0,1]]
            arrnum = data[:,[5,6]].astype(np.float)

            dstr = pd.DataFrame(arrstr,columns=['date','route'])
            dnum = pd.DataFrame(arrnum,columns=['from','to'])

            routes = dstr['route'] == 'C000001'
            from_ = dnum['from'] > 278.5

            if routes == True:
                if from_ == True:
                    print dstr,dnum
array_setter()

I had the same problem with too narrow output and solved it with putting ( import pandas as pd is assumed)

pd.set_option('display.width', 130)    

somewhere in the beginning of the file. Just for completeness I will also mention

pd.set_option('display.max_rows', 500)
pd.set_option('display.max_columns', 50)    

For more options and examples see pandas documentation

As for not iterating through *.txt files, can it be that your "for col" loop just needs extra indentation ? That's how it looks to me with your indentations as they are displayed in your post. Your "for file" loop is finished and only then your "for col" loop begins.

By the way, the indentations inside both for-loops are displayed as double indentations, which should not be.
