Python: Create a new list taking specific elements from a tuple and convert a string value to integer
Write a Python program to create a new list taking specific elements from a tuple and convert a string value to an integer.
Sample Solution:
Python Code :
# Create a list of tuples named 'student_data' containing student information
student_data = [('Alberto Franco','15/05/2002','35kg'), ('Gino Mcneill','17/05/2002','37kg'), ('Ryan Parkes','16/02/1999', '39kg'), ('Eesha Hinton','25/09/1998', '35kg')]
# Print the original data of student information
print("Original data:")
print(student_data)
# Use the map function and lambda expressions to extract student names, dates of birth, and weights
# and create new lists 'students_data_name', 'students_data_dob', and 'students_data_weight'
students_data_name = list(map(lambda x: x[0], student_data))
students_data_dob = list(map(lambda x: x[1], student_data))
students_data_weight = list(map(lambda x: int(x[2][:-2]), student_data))
# Print a message indicating the operation to be performed
print("\nStudent name:")
# Print the result of the map operation for student names
print(students_data_name)
# Print a message indicating the operation to be performed
print("Student date of birth:")
# Print the result of the map operation for student dates of birth
print(students_data_dob)
# Print a message indicating the operation to be performed
print("Student weight:")
# Print the result of the map operation for student weights
print(students_data_weight)
Sample Output:
Original data: [('Alberto Franco', '15/05/2002', '35kg'), ('Gino Mcneill', '17/05/2002', '37kg'), ('Ryan Parkes', '16/02/1999', '39kg'), ('Eesha Hinton', '25/09/1998', '35kg')] Student name: ['Alberto Franco', 'Gino Mcneill', 'Ryan Parkes', 'Eesha Hinton'] Student name: ['15/05/2002', '17/05/2002', '16/02/1999', '25/09/1998'] Student weight: [35, 37, 39, 35]
