文件 text.txt 的内容如下:

Python is a programming language.
Python is easy to learn.

以下程序统计单词 "Python" 在文件中出现的次数（要求Python后面是空格或行尾，且不跟标点），请补全代码横线处的内容：

count = 0
with open("text.txt", "r") as f:
    content = f.________ # 补全代码
    words = content.split()
    for word in words:
        if word == "Python":
            count += 1
print("Python出现次数:", count)
