+    """
+    Convert a number into a string that contains raindrop sounds corresponding to certain potential factors.
+
+    A factor is a number that evenly divides into another number, leaving no remainder.
+    The simplest way to test if one number is a factor of another is to use the modulo operation.
+
+    The rules of raindrops are that if a given number:
+
+    - has 3 as a factor, add 'Pling' to the result.
+    - has 5 as a factor, add 'Plang' to the result.
+    - has 7 as a factor, add 'Plong' to the result.
+    - does not have any of 3, 5, or 7 as a factor, the result should be the digits of the number.
+
+    Args:
+        number (int): The number to be converted into a raindrop sound string.
+
+    Returns:
+        str: The resulting raindrop sound string.
+
+    Examples:
+        >>> convert(28)
+        'Plong'
+        >>> convert(30)
+        'PlingPlang'
+        >>> convert(34)
+        '34'
+    """

+    if number % 3 == 0:
+        sounds.append('Pling')
+    if number % 5 == 0:
+        sounds.append('Plang')
+    if number % 7 == 0:
+        sounds.append('Plong')
