Python Print String To Text File

Question

I'm using Python to open a text document: text_file = open("Output.txt", "w") text_file.write("Purchase Amount: " 'TotalAmount') text_file.close() I want to substitute the value of a string variable TotalAmount into the text document. Can someone please let me know how to do this? Select the correct answer from above options

Answer 1

For the version Python2.6, it's preferred to use str.format()method:- with open("Output.txt", "w") as text_file: text_file.write("Purchase Amount: {0}".format(TotalAmount)) If you are using Python2.7 and higher versions you can use {} instead of {0} which we have used in Python 2.6:- with open("Output.txt", "w") as text_file: text_file.write("Purchase Amount: {}".format(TotalAmount)) If you are working with Python3.6 then you will have to use f-string which is introduced in Python3.6:- with open("Output.txt", "w") as text_file: print(f"Purchase Amount: {TotalAmount}", file=text_file) To know more about this you can have a look at the following video tutorial:-
