I don t understand why I cannot write to file in my python program. I have list of strings measurements. I want just write them to file. Instead of all strings it writes only 1 string. I cannot understand why. This is my piece of code:

fmeasur = open(fmeasur_name,  w )
line1st =  rev number, alg time
 
fmeasur.write(line1st)
for i in xrange(len(measurements)):
    fmeasur.write(measurements[i])
    print measurements[i]
fmeasur.close()

我可以看看看所有这些ring子,但档案中只有一个。 问题是什么?

最佳回答

我唯一可信的解释是,你多次执行上述守则,每次在<条码>中单列条目”(或至少last)。 页: 1

由于你重写了档案,而不是寄给它,因此,只有最后一套测量数据将出现在档案中,但all其中将登在屏幕上。

<><>>> 或者,你是否意味着数据是存在的,但测量之间没有新的界线? 采用<条码>印本;>fmeasur, 计量[i]而不是<条码>的确定最容易的方法。
