Missing parentheses in call to 'print'. Did you mean print(...)?

This is a syntax error message that appears when the code is missing parentheses in a print statement. The message suggests that the programmer may have meant to use the print() function.

For example, if the code contained:

print "Hello, world!"

It should be changed to:

print("Hello, world!")

This will fix the syntax error and properly execute the print statement.

SyntaxError: Missing parentheses in call to 'print'. Did you mean print

这个错误是由于在Python3中，print函数需要使用括号，而在Python2中则不需要。因此，如果你在Python3中运行Python2的代码，就会出现这个错误。解决这个问题的方法有两种：

1.在print函数中添加括号，例如：

print('Hello, world!')

改为：

print('Hello, world!')

2.将Python2的代码转换为Python3的代码。可以使用2to3工具来自动完成这个过程，也可以手动修改代码。

Missing parentheses in call to 'print'. Did you mean print(...)

This error message typically appears in Python when there are missing parentheses in a print statement.

For example, instead of writing:

print "Hello, world!"

You should write:

print("Hello, world!")

If you forget to include the parentheses, Python will interpret the statement as a function call without any arguments, which will result in a syntax error. The correct way to call the print function is to include the parentheses, like this:

print("Hello, world!")

If you see this error message in your code, check to make sure that all print statements include parentheses around the arguments.
