Program to print first character of elements inside a list

In this program, we will print first character of each element inside a list

Create a list of city names

city = ['Paris','New York','London','Tokyo']

Finding number of elements inside a list using len() function

l = len(city)
print('Number of elements in a list',l)

Creating a variable i and assigning 0 value to it

i = 0

Now using while loop to print first character from each element inside a list

while i < l:
    print(city[i][0])
    i+=1

Output

Number of elements in a list 4
P
N
L
T
