Assignment #3 - Mohammed Abdul Wasay

1. Python function that takes a list of words and return the longest word and the length of the longest one.

# function to find the longest word and its length in the list
def longestword(word):
    maxlen1 = len(word[0])
    temp = word[0]
 
    # for loop to traverse the list
    for i in word:
        if(len(i) > maxlen1):
 
            maxlen1 = len(i)
            temp = i
 
    print("The longest word is:", temp,
          " and its length is ", maxlen1)

list1 = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday","Friday","Saturday"]
longestword(list1)

The longest word is: Wednesday  and its length is  9

1. Python function to remove the nth index character from a nonempty string.

def remove_nth_char(str,n):
    # extracts 0 to n-1th index using slicing
    str_before_nth = str[:n]
 
    # extracts characters from n+1th index until the end
    str_after_nth = str[n+1:]
    print("String after removing the ", n, "th character is")
 
    # combining both the parts together
    print(str_before_nth + str_after_nth)

str1="yearning too learn python"
remove_nth_char(str1,11)

String after removing the  11 th character is
yearning to learn python

1. Python function to get the last part of a string before a specified character.

def getlastpart(txt, gchar):
    
    stringpart = txt.partition(gchar)
    
    print(stringpart)  

str3 = "docs.python.org"
getlastpart(str3,',')

('docs.python.org', '', '')

def get_lstpart_str(my_str, char):
    partitioned_string = my_str.rpartition(char)
    print(partitioned_string)

    #before_last_char = partitioned_string[0]

    #print(before_last_char)

a_string = "docs.python.org"
get_lstpart_str(a_string,'.')

('docs.python', '.', 'org')

b_str ="apple#banana#mango"
get_lstpart_str(b_str,'#')

('apple#banana', '#', 'mango')

txt = "apple#banana#cherry#orange"

# setting the maxsplit parameter to 1, will return a list with 2 elements!
x = txt.split("#", 1)

print(x)

['apple', 'banana#cherry#orange']

1. Python function to sort a string lexicographically.

def sortingbyLexi(my_string):
     
    # Split the my_string till where space is found.
    words = my_string.split()
     
    # sort() will sort the strings.
    words.sort()
 
    # Iterate i through 'words' to print the words
    # in alphabetical manner.
    for i in words:
        print( i )
 

sortingbyLexi("banana grapes apples oranges peaches mango")

apples
banana
grapes
mango
oranges
peaches

1. Python function to remove spaces from a given string.

# function to remove spaces from a given string 
import string

def remove(string):
    return "".join(string.split())

string = "H e l l o P y t h o n"
remove(string)

'HelloPython'
