1 program to find the longest word and its length:¶

In [1]:
a=[]
n= int(input("Enter the number of elements in list:"))
for x in range(0,n):
    element=input("Enter element" + str(x+1) + ":")
    a.append(element)
max1=len(a[0])
temp=a[0]
for i in a:
    if(len(i)>max1):
       max1=len(i)
       temp=i
print("The longest word is:")
print(temp)
print("the length of the longest word is:", len(temp))

Enter the number of elements in list:4
Enter element1:i
Enter element2:had
Enter element3:an
Enter element4:apple
The longest word is:
apple
the length of the longest word is: 5

2 program to remove the nthindex character from a nonempty string:¶

In [2]:
def remove_ch(str, n):
    first_part= str[:n]
    last_part= str[n+1:]
    return first_part+last_part
str = input("enter the string:")
n=int(input("enter the index of character to be removed:"))
print("modified string:",remove_ch(str,n))

enter the string:python
enter the index of character to be removed:3
modified string: pyton

4 program to sort a string lexicographically¶

In [2]:
def lexico_sort(s):
    return sorted(sorted(s), key= str.upper)
s= input("enter the string:")
print("modified string:",lexico_sort(s) )

enter the string:python
modified string: ['h', 'n', 'o', 'p', 't', 'y']
