Python Code:

# Import the OrderedDict class from the collections module
from collections import OrderedDict

# Create a string 'text_str'
text_str = "Python Exercises Practice Solution Exercises"

# Print a message to indicate the display of the original string
print("Original String:")

# Print the content of 'text_str'
print(text_str)

# Print a message to indicate the display after removing duplicate words from the string
print("\nAfter removing duplicate words from the said string:")

# Split 'text_str' into words, use OrderedDict to remove duplicates, and join the unique words
result = ' '.join(OrderedDict((w, w) for w in text_str.split()).keys())

# Print the result
print(result) 

Sample Output:

Original String:
