Basic Input/Output

Read a line of input as a string

s = input()

Katta: Echo echo

Read a string, either “Hello” or “Hallo”, and repeat it twice.

Intended solution:

Use a variable to store input: .. literalinclude:: ../../problems/echoecho/submissions/accepted/th.py

lines:

3-

Other solutions:

Since there are only two possible inputs, we can be less general, avoiding the variable but using selection:

if input() == "Hello":
    print("Hello")
    print("Hello")
else:
    print("Hallo")
    print("Hallo")

Wrong ideas:

a = input()
print(a)

a = input()
print(a)
a = input()
print(a)

Note

Output validation is lenient with respect to whitespace and letter case.
