但是使用的是writelines()传参数是列表没有问题但还是报错,经过网络查询算是找到了原因,writelines()函数确实是接收列表参数但是对这个列表参数是有要求的,列表要是str类型元素组成的列表,其他类型就会报错 下面是该函数定义说明位置 defwritelines(self, lines: List[AnyStr]) ->None:pass #List[AnyStr] 就是说明列...
它的行为实际上类似于一个名为write_all_of_these_strings(sequence)的虚方法。 下面是Python中的一种惯用方法,它将字符串列表写入文件,同时将每个字符串保持在自己的行中: lines = ['line1', 'line2'] with open('filename.txt', 'w') as f: f.write('\n'.join(lines)) 1. 2. 3. 这会帮你...
示例代码如下: # 1. 定义需要写入的行lines=["第一行内容","第二行内容","第三行内容"]# 2. 打开文件withopen('output.txt','w')asfile:# 3. 写入内容,添加换行符file.writelines([line+"\n"forlineinlines]) 1. 2. 3. 4. 5. 6. 7. 2.3 使用print函数 另外一种方式是利用print()函数,它...
而不是单引号,否则报错,在内存的第二行写上字符:isn't a>>>f=open('x','w')#以写的方式打开文件>>>f.writelines(lines)#将内存lines里的内容写入到文件对象f里>>>f.close()>>>f=open('x','r')#以读的方式打开文件some

>>> lines[1]="isn't a\n" #这⾥必须是双引号，⽽不是单引号，否则报错，在内存的第⼆⾏写上字符：isn't a >>> f=open('x','w') #以写的⽅式打开⽂件 >>> f.writelines(lines) #将内存lines⾥的内容写⼊到⽂件对象f⾥ >>> f.close()>>> f=open('x','r')...
