将python函数输出写入.txt文件

所以我有这些功能，旨在将其输出打印/写入文本文件。现在，当这些函数在python shell中打印其输出时，我便得到了所需的东西。当我尝试将这些输出写入文本文件时，事情变得不对劲了。

具体功能如下：

def printsection1(animals, station1, station2):
    for animal in animals:
        print(animal,'                 ',station1.get(animal, 0),'                   ',station2.get(animal, 0))

def printsection2(animals, station1, station2):
    for animal in animals:
        if station2.get(animal, 0)+station1.get(animal, 0) >= 4:
            print(animal)

def printsection3(animals, station1, station2):
    for animal in animals:
        print(animal,'                    ',int(station1.get(animal, 0))+int(station2.get(animal, 0)))

def printsection4(items):
    import statistics
    most_visits=[]
    for animal, date, station in items:
        most_visits.append(date[0:2]) 

    print(statistics.mode(most_visits))

我在main（）函数中写入文本文件的代码如下所示：

outfile.write("Number of times each animal visited each station:\n")
outfile.write("Animal ID           Station 1           Station 2 \n")
printsection1(animals, station1, station2)
outfile.write('\n')
outfile.write("============================================================ \n")

outfile.write("Animals that visited both stations at least 4 times \n")
printsection2(animals, station1, station2)
outfile.write('\n')
outfile.write("============================================================ \n")

outfile.write("Total number of visits for each animal \n")
printsection3(animals, station1, station2)
outfile.write('\n')
outfile.write("============================================================ \n")

outfile.write("Month that has the highest number of visits to the stations \n")
printsection4(items)

是否有一种简单的方法可以将函数的输出写入文本文件？我已经看到“ >>”运算符四处可见，但似乎无法正常运行。如果需要更多信息，我可以提供。

再次感谢！
