Print Call Stack

Write a Python program to print the current call stack.

Sample Solution:

Python Code:

 # Import the 'traceback' module.
import traceback

# Print an empty line for formatting.
print()

# Define a function 'f1' that calls the 'abc' function.
def f1():
    return abc()

# Define the 'abc' function that prints the current stack using 'traceback.print_stack()'.
def abc():
    traceback.print_stack()

# Call the 'f1' function, which, in turn, calls the 'abc' function.
f1()

# Print an empty line for formatting.
print()

Sample Output:

    f1()                                                                                                      
  File "7a070e70-25c4-11e7-bc90-3fdc1ec1c64d.py", line 3, in f1                                               
    def f1():return abc()                                                                                     
  File "7a070e70-25c4-11e7-bc90-3fdc1ec1c64d.py", line 4, in abc                                              
    def abc():traceback.print_stack()
