Concatenation
Concatentation is joining strings together.
The SQA will use ampersand (&), but Python uses plus (+) signs.
1 2 3 | #fullname = forename + ' ' + surname# |
String Length
The len() function will return the number of characters in a string.
1 2 3 4 5 | #pin = input("Enter your PIN:")pinLength = len(pin)print(f"That has {pinLength} characters")# |
Characters and ASCII (for Higher)
1 2 3 4 5 6 7 8 | ## ord - returns the number representing the unicode code of a specified number = ord("A")# chr - returns the character that represents the specifiedletter = chr(65) # |
String Slicing (Substrings) (for Higher)
Each character in a string has an index number, starting at zero.
index 0 1 2 3 4 5 6 7 8 string A n d e r s o n !
Picking any single character:
1 2 3 4 5 6 | #firstLetter = string[0]secondLetter = string[1]#lastLetter = string[-1]# |
Picking several characters:
Give the index of the start letter, and the index of ending letter plus one.
1 2 3 4 | #letters2and3 = string[2:4]letters4to7 = string[4:8]# |
