How to print array elements into string without string function-CodePudding

Hi so I wanted to put array elements to become a string. The objective is I wanted to put the string in print function. For instance:

Given an array of [1, 2, 0, 1] Is there any way to make the elements to become one string (i.e. to be 1201)? Lets say the string variable is '''array_elements''' I want to have the output of:

the elements are: 1201.

So of course what I should do to the print function is:

print("the elements are: "   str(array_elements), ".")

The problem is, I'm a python beginner and i don't know how to solve the problem without using string function (since this is what google told me to do, but I'm now allowed to use that." What I could think of is by using looping but I still can't manage to make it as one string variable

CodePudding user response：

"".join(str(x) for x in [1, 2, 0, 1])

You need to convert integers to string, since you want to have a string in the end. this is what happens under the hood anyway

However if you actually want an integer this is another task. Then you can do this:

from functools import reduce
reduce(lambda a, b: 10 * a   b, [1, 2, 0, 1])

Another option is to print the elements one by one in a loop, using the end="" argument to avoid ending the line before you're ready:

print("the elements are:", end=" ")

for x in [1, 2, 0, 1]:
  print(x, end="")

print()
