python删去空行

要在Python中删除空行，你可以使用不同的方法。以下是两种常见的方法:

方法一:

file1 = open('text1.txt', 'r', encoding='utf-8') # 打开要去除空行的文件
file2 = open('text2.txt', 'w', encoding='utf-8') # 创建一个新文件用于存储没有空行的内容
try:
    for line in file1.readlines():
        if line == '\n': # 如果该行是空行
            line = line.strip("\n") # 去除该行的换行符
        file2.write(line) # 将处理后的行写入新文件
finally:
    file1.close() # 关闭文件1
    file2.close() # 关闭文件2

方法二:

mystr = 'aiyuechuang\n\n\n2021' # 要处理的字符串
print("".join([s for s in mystr.splitlines(True) if s.strip()])) # 使用列表推导式去除每行的空白字符并拼接起来

这样，你就可以使用这两种方法中的任意一种来删除Python中的空行。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
