[英]Extract columns from Excel using Python
I have an Excel file with the ff: row/col structure 我有一个带有ff:row / col结构的Excel文件
ID English Spanish French
1 Hello Hilo Halu
2 Hi Hye Ghi
3 Bus Buzz Bas
I would like to read the Excel file, extract the row and col values, and create 3 new files base on the columns English, Spanish, and French. 我想阅读Excel文件,提取行和列值,并根据英语,西班牙语和法语列创建3个新文件。
So I would have something like: 所以我会有类似的东西:
English File: 英文文件:
"1" = "Hello"
"2" = "Hi"
"3" = "Bus"
I've been using xlrd. 我一直在使用xlrd。 I can open, read, and print the contents of the file.
我可以打开,阅读和打印文件的内容。 However, this is what I get using this command (with the Excel file already open):
但是,这是我使用此命令(Excel文件已打开):
for index in xrange(0,2):
theWord = '\n' + str(sh.col_values(index, start_rowx=index, end_rowx=1)) + '=' + str(sh.col_values(index+1, start_rowx=index, end_rowx = 1))
print theWord
OUTPUT: OUTPUT:
[u'Parameter/Variable/Key/String']=[u'ENGLISH'] <-- is this a list?, didn't the str() use to strip it out?
What's the u doing there? 什么是ü做什么呢? How can I remove the square brackets?
如何删除方括号?
The u
means it is a unicode string, it gets put there when you call str()
. u
意思是它是一个unicode字符串,当你调用str()
时它被放在那里。 If you write the string out to a file it wont be there. 如果你将字符串写入文件,它就不会存在。 What you are getting is 1 row from the column.
你得到的是列中的一行。 It's because you are using
end_rowx=1
it returns a list with one element. 这是因为你使用的是
end_rowx=1
它返回一个包含一个元素的列表。
Try getting the column value lists: 尝试获取列值列表:
ids = sh.col_values(0, start_rowx=1)
english = sh.col_values(1, start_rowx=1)
spanish = sh.col_values(2, start_rowx=1)
french = sh.col_values(3, start_rowx=1)
and then you can zip
them into tuple lists: 然后你可以将它们
zip
成元组列表:
english_with_IDS = zip(ids, english)
spanish_with_IDS = zip(ids, spanish)
french_with_IDS = zip(ids, french)
Which are in the form: 其形式如下:
("1", "Hello"),("2", "Hi"), ("3", "Bus")
If you want to print the pairs: 如果要打印对:
for id, word in english_with_IDS:
print id + "=" + word
col_values
returns a list of column values, if you want single values you can call sh.cell_value(rowx, cellx)
. col_values
返回列值列表,如果您想要单个值,可以调用sh.cell_value(rowx, cellx)
。
import xlrd
sh = xlrd.open_workbook('input.xls').sheet_by_index(0)
english = open("english.txt", 'w')
spanish = open("spanish.txt", 'w')
french = open("french.txt", 'w')
try:
for rownum in range(sh.nrows):
english.write(str(rownum)+ " = " +str(sh.cell(rownum, 0).value)+"\n")
spanish.write(str(rownum)+ " = " +str(sh.cell(rownum, 1).value)+"\n")
french.write(str(rownum)+ " = " +str(sh.cell(rownum, 2).value)+"\n")
finally:
english.close()
spanish.close()
french.close()
In [1]: import pandas as pd
In [2]: df = pd.ExcelFile('test.xls').parse('Sheet1', index_col=0) # reads file
In [3]: df.index = df.index.map(int)
In [4]: for col in df.columns:
...: column = df[col]
...: column.to_csv(column.name, sep='=') # writes each column to a file
...: # with filename == column name
In [5]: !cat English # English file content
1=Hello
2=Hi
