Is there any way so I can convert my given code to one line?-CodePudding

Here is the question: Define a function named convert that takes a list of numbers as its only parameter and returns a list of each number converted to a string.

For example, the call convert([1, 2, 3]) should return ["1", "2", "3"].

And this is my code:

def convert(li):
for i in range(len(li)): li[i] = str(li[i])
return li

But this will give me error as another line is used. How do i convert the code to one line?

CodePudding user response：

You could use

convert = lambda li: list(map(str, li))

or a list comprehension:

convert = lambda li: [str(e) for e in li]

CodePudding user response：

Here's a quick list comprehension to do this in a line.

def convert(li):
    # For each item in the list, convert the integer to string:
    print([str(i) for i in li]) 

convert([1, 2, 3])

I can offer this solution:

def convert(li):
    return list(map(str, li))
