I am a total beginner and have been looking at http://en.wikibooks.org/wiki/Python_Programming/Conditional_Statements but I can not understand the problem here. It is pretty simple, if the user enters y it should print this will do the calculation although I get a syntax error on IF answer=="y"
answer = str(input("Is the information correct? Enter Y for yes or N for no")) proceed="y" or "Y" If answer==proceed: print("this will do the calculation"): else: exit()

We can perform string comparisons using the if statement. We can use relational operators with the strings to perform basic comparisons.
Using the == (equal to) operator for comparing two strings If you simply require comparing the values of two variables then you may use the '==' operator. If strings are same, it evaluates as True, otherwise False.
The if string rule is used to compare two constant dates which cannot be changed, and it will give the result if the condition is true. The example for the if string statement code is given below.
Answer 514a8bea4a9e0e2522000cf1 You can use multiple else if but each of them must have opening and closing curly braces {} . You can replace if with switch statement which is simpler but only for comparing same variable.
Even once you fixed the mis-cased if and improper indentation in your code, it wouldn't work as you probably expected. To check a string against a set of strings, use in. Here's how you'd do it (and note that if is all lowercase and that the code within the if block is indented one level).
One approach:
if answer in ['y', 'Y', 'yes', 'Yes', 'YES']: print("this will do the calculation") Another:
if answer.lower() in ['y', 'yes']: print("this will do the calculation") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
