Strings & I/O

≈ 25 min

A string is text. You can join strings with + (concatenation) and measure them with len():

greeting = "Hello, " + name n = len("hello") # 5

Strings have handy methods: "cape town".upper() → "CAPE TOWN", " hi ".strip() → "hi".

print(...) sends text to the screen; input(...) reads a line the user types (returns a string).

Code practice

Write a function greet(name) that returns the string "Hello, " followed by the name. For example greet("Zanele") returns "Hello, Zanele".
