Question

python 3

1. The Euler's number e is a mathematical constant, which can be calculated as the sum of the infinite series: c--+*+ 1*2 + 1x2x3 + 1*2*3*4+... Write a function Approxe(n) to approximate the value of e, where n is the upper limit of k. 2. Write a function missing Char(astring, n) to return a new string where the character at index n has been removed. If n is not a valid index, i.e., out of the range of the string length, then no character will be removed. For example: missing Char("love", 0) "ove" missing Char("love", 2) "loe" missing Char("love", 4) - "love"

1->

# do comment if any problem arises
# Code

#this function calculates factorial of given number
def fact(num):
factorial=1
for i in range(1,num+1):
factorial*=i
return factorial
#this function calculates approximate value of e for a given n
def Approx(n):
e=0
for i in range(n+1):
e+=1/fact(i)
return e
  
#testing above function
print(Approx(10))

Screenshot of code:

4 5 #this function calculates factorial of given number def fact(num): factorial=1 for i in range(1, num+1): factorial*=i return factorial #this function calculates approximate value of e for a given n def Approx(n): e=0 for i in range(n+1): e+=1/fact(i) return e 10 11 12 13 14 15 16 17 18 #testing above function print (Approx(10),

# Code

#this function deletes character of a given string at given index
def missingChar(astring,n):
final_string=""
#iterate over given string
for i in range(len(astring)):
#if i is not equal to given index then append current character to final string
if i!=n:
final_string+=astring[i]
return final_string

#testing above function
print(missingChar("love",0))
print(missingChar("love",2))
print(missingChar("love",4))

Screenshot of code:

4 5 #this function deletes character of a given string at given index def missingchar(astring, n): final_string="" #iterate over given string for i in range(len(astring): #if i is not equal to given index then append current character to final string if in: final_string+=astring[i] return final_string 13 14 15 16 17 #testing above function print(missingchar("love",0)), print(missingchar("love",2)), print(missingchar("love",4)),

Output:

ove loe love
