#  Python Print String To Text File

text_file = open("Output.txt", "w")
text_file.write("Purchase Amount: %s" % TotalAmount)
text_file.close()

#  If you use a context manager, the file is closed automatically for you

with open("Output.txt", "w") as text_file:
    text_file.write("Purchase Amount: %s" % TotalAmount)

#  If you're using Python2.6 or higher, it's preferred to use
#  str.format()

with open("Output.txt", "w") as text_file:
    text_file.write("Purchase Amount: {0}".format(TotalAmount))

#  For python2.7 and higher you can use {} instead of {0}
#  
#  In Python3, there is an optional file parameter to the print function

with open("Output.txt", "w") as text_file:
    print("Purchase Amount: {}".format(TotalAmount), file=text_file)

#  Python3.6 introduced f-strings
#  (https://docs.python.org/3/whatsnew/3.6.htmlpep-498-formatted-string-
#  literals) for another alternative

with open("Output.txt", "w") as text_file:
    print(f"Purchase Amount: {TotalAmount}", file=text_file)
