Our task is to convert a list of characters into a single string. For example, if the input is ['H', 'e', 'l', 'l', 'o'], the output should be "Hello".
Using join()We can convert a list of characters into a string using join() method, this method concatenates the list elements (which should be string type) into one string.
Python
a = ['P', 'y', 't', 'h', 'o', 'n']
# Convert list of characters to string
s = ''.join(a)
print(s)
Explanation: ''.join(a) joins all elements in a using an empty string as the separator.
Using reduce()reduce() function applies a function cumulatively to the elements of the list, reducing them to a single value.
Python
from functools import reduce
a = ['P', 'y', 't', 'h', 'o', 'n']
res = reduce(lambda x, y: x + y, a)
print(res)
Explanation:
If we want to join all the characters of the given list without using any inbuilt method then we can use a for loop.
Python
a = ['P', 'y', 't', 'h', 'o', 'n']
s = ''
# Loop through each character in list 'a' and add it to string 's'
for c in a:
s += c
print(s)
Explanation: Iterates through a, adding each character to res and builds the final string step by step.
