python怎么过滤掉空行?

# coding = utf-8

def clearBlankLine():

    file1 = open('text1.txt', 'r', encoding='utf-8') # 要去掉空行的文件

    file2 = open('text2.txt', 'w', encoding='utf-8') # 生成没有空行的文件

    try:

        for line in file1.readlines():

            if line == '\n':

                line = line.strip("\n")

            file2.write(line)

    finally:

        file1.close()

        file2.close()

if __name__ == '__main__':

    clearBlankLine()
