【问题描述】：

我有一些读物：

ATCAAAGTCCCGTAGGTACGGGAAATGCAAAAAAA GGGCTAGGTAGGGATTGCCTAGTCAACTGGGGGGGG TAGCTAGGTAGGGATTGCCTAGTCAACTGGCCCGG

...

现在，我想把每个读写左边的12个碱基切到一个文件中：

f2 = open("./read1.csv","w")
with open('../001.fastq') as reader:
     for index, line in enumerate(reader):
         if index % 4 == 1:
             f2.write(line[:12]+'\n')
f2.close()

我想知道怎么写一个xlsx文件

【问题讨论】：

你能显示你想要的输出吗？
输出是：ATCAAAGTCCCG GGGCTAGGTAGG TAGCTAGGTAGG
您询问的是 XSLX 还是 CSV 文件？
代码是写一个csv文件，但是我想保存xlsx文件，不知道怎么修改

【解决方案1】：

每次读取有 4 行

ATCAAAGTCCCGTAGGTACGGGAAATGCAAAAAAA

TAGCTAGGTAGGGATTGCCTAGTCAACTGGCCCGG

JJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJ

对于这个例子，输出是：

ATCAAAGTCCCG

GGGCTAGGTAGG

请遵守指南并编辑您的原始问题（并删除此答案）。这些额外的“帖子”仅供回答（cmets 要求澄清，添加一些补充或非必要信息和类似内容），而原始问题是唯一一个与它相关的地方。我知道这可能会首先令人困惑。顺便说一句，欢迎使用 stackoverflow。

【解决方案2】：

假设您使用的是 Windows 并安装了 Excel。有多个库可以使从 python 中使用 Excel 成为可能。其中我只使用过win32com.client，但我很满意。我认为它默认带有 anaconda，但如果没有，您可以从这里下载它：https://github.com/mhammond/pywin32/releases（不要忘记选择适当的版本/架构）。以下是对最重要功能的简要参考：

from win32com.client import Dispatch  # import the necessary library

xlApp = Dispatch("Excel.Application") # starts excel
xlApp.Visible = False                 # hides window (this makes things a bit faster)
xlBook = xlApp.Workbooks.Open( fullPathToXlsx ) # opens an existing workbook

xlSheet = xlBook.Sheets(3)            # which sheet you want to use, indexing starts from 1!
print [sheet.Name for sheet in xlBook.Sheets] # if it is not the one you want you can see their order this way
xlSheet = xlBook.Sheets(sheetName)    # or you can use its name

xlSheet.Cells(row, col).Value = newValue # newValue is what you want to assign to the cell, row and col indexing starts from 1

xlApp.DisplayAlerts = False           # turns off any affirmation popup
xlBook.Save()                         # saving workbook
xlBook.SaveAs(newFullPath)            # saving as...

xlBook.Close()                        # close workbook
xlApp.Quit()                          # exit application

您可能希望在列/行索引和“字母表示”之间进行转换（我的意思是左上角单元格的“A1”等）。这是我用来做的：

def cellStringToNum(aStr):
    """
    returns an excel sheet cell reference as numbers in a list as [col, row]
    """
    import string

    colS = ""
    for i in xrange(len(aStr)):
        if aStr[i] in string.ascii_uppercase:
            colS += aStr[i]
        else:
            row = int(aStr[i:])
            break
    col = 0
    for i in xrange(len(colS)):
        col += (string.ascii_uppercase.find(colS[len(colS)-1-i])+1)*(26**i)
    return [col, row]

def cellNumToString(col, row):
    import string

    colS = string.ascii_uppercase[col % 26 - 1]
    if col % 26 == 0:
        col -= 26
    else:
        col -= col % 26
    while col != 0:
        col /= 26
        colS = string.ascii_uppercase[col % 26 - 1] + colS
        if col % 26 == 0:
            col -= 26
        else:
            col -= col % 26
    return colS+str(row)
