python - 语法错误 : f-string: expecting '}'

Question

我这里有问题。
我不知道为什么这段代码不起作用。

newline = '\n'
tasks_choosen = ['markup', 'media', 'python_api', 'script', 'style', 'vue']
print(f'{ newline }### Initializing project with the following tasks: { ' '.join(tasks_choosen) }.{ newline }')

错误:

File "new-gulp-project.py", line 85

print(f'{ newline }### Initializing project with the following tasks: { ' '.join(tasks_choosen) }.{ newline }')

SyntaxError: f-string: expecting '}'

谁能帮我？
谢谢

因为您使用了两次单引号，所以您会得到:print(f'{ newline }### Initializing project with the following tasks: { ' 而不是

print(f'{ newline }### Initializing project with the following tasks: { ' '.join(tasks_choosen) }.{ newline }')

在里面使用双引号:

print(f'{ newline }### Initializing project with the following tasks: { " ".join(tasks_choosen) }.{ newline }')
