sequence item 1: expected string, list found
我从文件中提取了一些数据，并准备将其写入另一个文件。但我的程序返回错误：sequence item 1: expected string, list found
报错的代码如下
file = open('file1.txt','r')
file2 = open('file2.txt','w')
buffer = []
rec = file.readlines()
for line in rec :
field = line.split()
term1 = field
buffer.append(term1)
term2 = field
buffer.append
file2.write(buffer)# <== error
file.close()
file2.close()
试试str.join：
file2.write(' '.join(buffer))
file2.write( str(buffer) )
说明： str(anything)将任何python对象转换为其字符串表示形式。类似于你得到的输出print(anything)，
