Question

我正在尝试创建/写入txt文件，但是，我从https://www.guru99.com/reading-and-writing-files-in-python.html获得的代码未呈现。

def main():

f = open("JTF.txt", "w+")

for i in range(10)
    f.write("This is line %d\r\n" % (i+1))

f.close()

if __name__=="__main__":
    main()

# The error i am receiving when I run the above code is as follows:
#     def main()
#             ^
# SyntaxError: invalid syntax

Python使用空格块语法。另外，在for循环之后，您需要添加:

def main():
    f = open("JTF.txt", "w+")

    for i in range(10):
        f.write("This is line %d\r\n" % (i+1))

    f.close()

if __name__=="__main__":
    main()
