Program to assign values of tuples to several variables

by

In this python tuple program, we will assign values of tuples to several variables and print them.

Steps to solve the program
  1. Create a tuple.
  2. Assign values of tuples to several variables by using variable_names=tuple.
  3. Print the variable name and their value.
				
					tup =  (6,7,3)
(a,b,c) = tup
print("a: ",a)
print("b: ",b)
print("c: ",c)

Output :

				
					a:  6
b:  7
c:  3

Steps to solve the program
  1. Create a tuple.
  2. Find the element from the tuple having index number 2 using tuple_name[index number].
  3. Print the output.

Program to create a tuple with different datatypes

by

In this python tuple program, we will create a tuple with different datatypes.

Steps to solve the program
  1. You can simply create a tuple with different datatypes by adding elements with different datatypes in () to create a  tuple.
  2. Print the output.
				
					tup = (2.6,1,'Python',True,[5, 6, 7],(5, 1, 4),{'a':123,'b':456})
print("Tuple: ",tup)

Output :

				
					Tuple:  (2.6, 1, 'Python', True, [5, 6, 7], (5, 1, 4), {'a': 123, 'b': 456})

Create a list of tuples from a list having a number and its square in each tuple

by

In this python tuple program, we will create a list of tuples from a list having a number and its square in each tuple.

Steps to solve the program
  1. Take a list as input.
  2. Use the list comprehension method to create a list of tuples from a list having a number and its square in each tuple.
  3. Use for loop to iterate over elements in the list and use pow() to get the square of the elements.
  4. Perform the above operations inside a list to achieve list comprehension.
  5. Print the output.
				
					list1 = [4,6,3,8]

tup = [(val, pow(val, 2)) for val in list1]
print(tup)

Output :

				
					[(4, 16), (6, 36), (3, 9), (8, 64)]

Find the minimum value from a tuple

by

In this python tuple program, we will find the minimum value from a tuple.

Steps to solve the program
  1. Create a tuple.
  2. Find the minimum value from a tuple using min().
  3. Print the output.
				
					tup = (36,5,79,25)
print("Minimum value: ",min(tup))

Output :

				
					Minimum value:  5

Find the maximum value from a tuple

by

In this python tuple program, we will find the maximum value from a tuple.

Steps to solve the program
  1. Create a tuple.
  2. Find the maximum value from a tuple using max().
  3. Print the output.
				
					tup = (41, 15, 69, 55)
print("Maximum value: ",max(tup))

Output :

				
					Maximum value:  69
Solution2 :
				
					# take input tuple with multiple values
tup = (41, 15, 69, 101, 55)
# initiate a variable to store max value
max_val = 0
# interate through tuple values using loop
for val in tup:
    # check if val is greater than max_val
    if val > max_val:
        # assign variable value to max_val.
        max_val = val
    else:
        continue

print("maximum value :", max_val)

Output :

				
					maximum value : 101

Program to create a tuple with 2 lists of data

by

In this python tuple program, we will create a tuple with 2 lists.

Steps to solve the program
  1. Take two lists as input.
  2. Combine elements having the same index no using zip() and convert that list into a tuple using tuple().
  3. Print the output.
				
					list1 = [4, 6, 8]
list2 = [7, 1, 4]
tup =tuple(zip(list1,list2))
print(tup)

Output :

				
					((4, 7), (6, 1), (8, 4))

Python Pandas program to replace NaNs with the median value in a DataFrame

by

In this python pandas program, we will replace NaNs with the median value using the pandas library.

Steps to solve the program
  1. Import pandas library as pd.
  2. Create a dataframe using pd.DataFrame().
  3. Now replace the NaN values in the age column with the median value of the same column using df[‘Age’].fillna(df[‘Age’].median(),inplace=True).
  4. Print the output.
				
					import pandas as pd
import numpy as np
df = pd.DataFrame({'Sr.no.':[1,2,3,4],
                   'Name':['Alex','John','Peter','Klaus'],
                   'Age':[30,np.nan,29,22]})
print("Original Dataframe: \n",df)
df['Age'].fillna(df['Age'].median(),inplace=True)
print("After replacing missing values by mean: \n",df)

Output :

				
					Original Dataframe: 
    Sr.no.   Name   Age
0       1   Alex  30.0
1       2   John   NaN
2       3  Peter  29.0
3       4  Klaus  22.0
After replacing missing values by mean: 
    Sr.no.   Name   Age
0       1   Alex  30.0
1       2   John  29.0
2       3  Peter  29.0
3       4  Klaus  22.0
