In Python, we can perform various operations on strings like finding the length of a string, slicing a string, and looping through a string.
To find the length of a string, we can use the built-in len() function. For example:
fruit = "Mango"
len1 = len(fruit)
print(len1)
The output will be 5 as there are 5 characters in the string "Mango".
To slice a string, we can specify the start and end index of the substring we want to extract. For example:
pie = "ApplePie"
print(pie[:5]) #Slicing from Start
print(pie[5:]) #Slicing till End
print(pie[2:6]) #Slicing in between
print(pie[-8:]) #Slicing using negative index
# In this case, the [-8:] notation specifies a slice that starts from the eighth last element and goes until the end of the list.
The output will be:
Apple
Pie
pleP
ApplePie
To loop through a string, we can use a for loop. Since strings are iterable, we can loop through each character in the string. For example:
alphabets = "ABCDE"
for i in alphabets:
print(i)
The output will be:
A
B
C
D
E
We can use these operations to manipulate and work with strings in Python.
