Python连接字符串和列表

Question

I have a list and string:

fruits = ['banana', 'apple', 'plum']
mystr = 'i like the following fruits: '

How can I concatenate them so I get (keeping in mind that the enum may change size) 'i like the following fruits: banana, apple, plum'

Answer 1

Join the list, then add the strings.

print mystr + ', '.join(fruits)

And don't use the name of a built-in type ( str ) as a variable name.

Answer 2

You can use this code,

fruits = ['banana', 'apple', 'plum', 'pineapple', 'cherry']
mystr = 'i like the following fruits: '
print (mystr + ', '.join(fruits))

The above code will return the output as below:

i like the following fruits: banana, apple, plum, pineapple, cherry

Answer 3

You can use str.join .

result = "i like the following fruits: "+', '.join(fruits)

(assuming fruits only contains strings). If fruits contains a non-string, you can convert it easily by creating a generator expression on the fly:

', '.join(str(f) for f in fruits)

Answer 4

You're going to have a problem if you name your variables the same as Python built-ins. Otherwise this would work:

s = s + ', '.join([str(fruit) for fruit in fruits])

Answer 5

下面的简单代码将起作用：

print(mystr, fruits)
