Convert a List to a Python string

This post will discuss how to convert a list to a string in Python.

The preferred and fast way to concatenate the strings in iterable is with the str.join() function. The following code example shows how to implement this:

if __name__ == '__main__':

chars = ['1', '2', '3']

s = ''.join(chars)

print(s) # 123

Note that TypeError will be raised for any numeric values in iterable. To convert a list of integers to a string, you have to first convert each of the non-string values present in the iterable to a string. You can do this in the following ways:

1. Using Generator Expression

You can use a generator to easily convert the list of integers to a string, as shown below:

if __name__ == '__main__':

nums = [1, 2, 3]

s = ''.join(str(x) for x in nums)

print(s) # 123

2. Using `map()` function

It is preferable to use the map() function instead, which efficiently converts a list of integers to a string.

if __name__ == '__main__':

nums = [1, 2, 3]

s = ''.join(map(str, nums))

print(s) # 123

That’s all about converting a List to a string in Python.
