希望在每次迭代中都用换行符编写，但无法解决。我从abc.txt使用函数getUser（）和getFriends（）读取随机字符串。并写入文本文件new_file.txt，但在每次迭代的第一行中写入
输出：['Larina'] ['Oormi'，'Palky'] ['Kavia'] ['Chakradhara'，'Chunni']
我需要这种格式：
['Larina'] ['Oormi'，'Palky']
['Kavia'] ['Chakrahari'，'Chunni']
with open("new_file.txt", "wb") as sink:
for i in range(0,2):
print>>sink, getUser(),getFriends()
#print>>sink,("\n")
def getUser():
with open("abc.txt", "rb") as source:
lines = [line.rstrip() for line in source]
random_choice = random.sample(lines, 1)
source.close()
return(random_choice);
def getFriends():
with open("abc.txt", "rb") as source:
lines = source.read().splitlines()
random_choice = random.sample(lines, 2)
source.close()
return(random_choice);
您不必关闭，source因为with语句可以帮您完成。
试试下面的代码：
with open("new_file.txt", "wb") as sink:
for i in range(0,2):
sink.write("%s %s\n" % (str(getUser()), str(getFriends())))
def getUser():
with open("abc.txt", "rb") as source:
lines = [line.rstrip() for line in source]
random_choice = random.sample(lines, 1)
return(random_choice);
def getFriends():
with open("abc.txt", "rb") as source:
lines = source.read().splitlines()
random_choice = random.sample(lines, 2)
return(random_choice)
