Python divmod() Method with Examples

Python / By

In the previous article, we have discussed Python int() Method with Examples
divmod() Method in Python:

When argument1 (dividend) is divided by argument2, the divmod() function returns a tuple containing the quotient and the remainder (divisor).

Syntax:

divmod(dividend, divisor)

Parameter Values:

dividend: It is a number. The number by which you wish to divide

divisor: It is a number. The number you wish to divide by.

Return Value:

The divmod() Function returns

  • (q, r) – a pair of numbers (a tuple) made up of the quotient q and the remainder r.
  • If dividend and divisor are integers, the result of divmod() is (q// r, dividend %divisor ).
  • If either dividend or divisor is a float, the resulting expression is (q, dividend %divisor ). In this case, q represents the entire quotient.

Examples:

Example1:

Input:

Given first number(dividend)= 3
Given second number(divisor) = 5

Output:

A Tuple containing the quotient and the remainder = (0, 3)

Example2:

Python List index() Method with Examples

Python / By

In the previous article, we have discussed Python List extend() Method with Examples
List in Python:

Lists in Python are mutable sequences. They are extremely similar to tuples, except they do not have immutability constraints. Lists are often used to store collections of homogeneous things, but there is nothing stopping you from storing collections of heterogeneous items as well.

List index() Method in Python:

The index() method returns the position in the given list of the given element.

Syntax:

gvnlist.index(element, start, end)

Parameter Values: 

The list index() method can accept up to three arguments:

element – the to-be-searched element

start (optional) – Begin searching from this index

end (optional) – Search the element all the way up to this index

Return Value:

The index() method returns the index of the specified list element.
A ValueError exception is thrown if the element is not found.

Note:

Only the first occurrence of the matching element is returned by the index() method.

Examples:

Example1:

Input:

Given List = ['hello', 'this', 'is', 'python', 'programs']
Given Element = 'this'

Output:

The given element { this } in the given list ['hello', 'this', 'is', 'python', 'programs'] is present at the index :
1

Example2:

Input:

Given List = ['hello', 'this', 'is', 'python', 'programs']
Given Element = 'btechgeeks'

Output:

Traceback (most recent call last):

# Give the string as user input using the input() function and store it in a variable.
gvn_str = input("Enter some Random String = ")
# Give the old value as user input using the input() function and store it in another variable.
old_valu = input("Enter some Random String(oldvalue) = ")
# Give the new value as user input using the input() function and store it in another variable.
new_valu = input("Enter some Random String(newvalue) = ")
# Give count as user input using the int(input()) function and 
# store it in another variable.
gvn_cnt = int(input("Enter some random number = "))
# Pass the given old value, new value, count as arguments to the replace()
# function for the given string to replace the old value with a new value
# in a given string. Here count is a number indicating how many occurrences
# of the old value should be replaced.
# Store it in another variable.
rslt = gvn_str.replace(old_valu, new_valu, gvn_cnt)
# Print the above result i.e, The given string after replacing the old value
# with the given new value.
print("The given string after replacing oldvalue{",
      old_valu, "} with new value{", new_valu, "} is:")
print(rslt)

Output:

Enter some Random String = welcome to to python to to programs
Enter some Random String(oldvalue) = to
Enter some Random String(newvalue) = all
Enter some random number = 3
The given string after replacing oldvalue{ to } with new value{ all } is:
welcome all all python all to programs
