[英]Python, writing CSV file has extra blank rows
I have a piece of python code which is supposed to open (or create) a CSV file and append a new row to the end of it. 我有一段python代码,应该打开(或创建)CSV文件并将新行添加到它的末尾。 However, there is an extra blank line added between each entry. 但是,在每个条目之间添加了一个额外的空白行。 Is there a way to avoid this? 有办法避免这种情况吗?
I have around 500 instances of the script which all access the same file, though (in theory) they should access the file at different times. 我有大约500个脚本实例,它们全部都访问同一文件,尽管(理论上)它们应在不同时间访问该文件。
def writeBest(fileName, savePath, data):
# Create a filename
name = "BEST_" + fileName + ".csv"
# Create the complete filename including the absolute path
completePath = os.path.join(savePath, fileName)
# Check if directory exists
if not os.path.exists(completePath):
os.makedirs(completePath)
completeName = os.path.join(completePath, name)
# Write the data to a file
theFile = open(completeName, 'wb')
writer = csv.writer(theFile, quoting=csv.QUOTE_ALL)
writer.writerow(data)
# Close the file
theFile.close()
Problem answered through comments. 问题通过评论回答。 The issue was using the wb
mode not ab
mode. 问题是使用wb
模式而不是ab
模式。
“ b”选项对我有用,请查看API文档: https : //docs.python.org/2/library/functions.html? highlight = open# open
