Question

我正在尝试以可呈现的方式格式化此数据文件。原始数据是：

我不知道如何摆脱每个字符串前面的空白，以及如何在下一行保存数据。

我试过了：

       Sodium
            Specimen insufficient for test(s)
       Potassium
            Specimen insufficient for test(s)
       Chloride
            Specimen insufficient for test(s)
       Bicarbonate

       eGFR (MDRD formula)                     >60      mL/min/1.73 m2
            MDRD-derived estimation of GFR may significantly underestimate true GFR
            in patients with GFR > 60 mL/min/1.73m^2.  It may also be unreliable in
            the case of: age <18 years or >70 years; pregnancy; serious co-morbid
            conditions; acute renal failure; extremes of body habitus/unusual diet,
            gross oedema. The MDRD-eGFR used here does not employ an ethnic factor
            for race.

但它给了我这个：

fin = open( 'results.txt', "r" )
lines = fin.read()
fin.close()
# test it ...
data = ""
for line in lines:
    data = data + line.strip();
print data

当然还有更好的方法来使用制表符空格和换行符来格式化文本吗？我错过了什么？

Answer 1

当您致电line.strip()时，您将从字符串的开头和结尾删除所有空格，包括换行符。因此，当您data = data + line.strip()创建长字符串而没有您在打印时看到的换行符。如果你只是想在没有前导空格的情况下打印线条，你可以将其剥离：

for line in lines:
    data = data + line.lstrip()
print data

或者你可以在剥离它们时打印掉剥离的线条（打印会将换行符重新插入）：

for line in lines:
    print line.strip()

P.S。不要在Python语句的末尾添加分号。

格式化字符串的文本文件是可读的
