Comparison between string manipulation functions in python language and pseudo code within the IGCSE A level syllabus https://elmalla.info/blog/64-private-lesson-resources

1. String manipulation functions
Pseudo Code Python
ThisString[P]
//Counts from 1
CHR(i : INTEGER)
//RETURNS CHAR whose ASCII
value is i
ASC(ch)
//RETURNS the ASCII INTEGER
value of character ch
LENGTH(S : STRING)
//RETURNS INTEGER
LEFT(S : STRING, L : INTEGER)
//RETURNS STRING
LEFT(“JOY”, 2) //JO
RIGHT(S: STRING, L : INTEGER)
//RETURNS STRING
RIGHT(“Sami”, 2) //mi
MID(S : STRING, P: INTEGER, L :
INTEGER)
//RETURNS STRING
MID (“SAMI”, 2,3) //AMI
LCASE(Ch : CHAR)
//RETURNS CHAR
UCASE(Ch : CHAR)
ThisString[P]
#Counts from 0
chr(i)
ord(‘A’)
len(S)
S[0:L]
#slicing
S[-L:]
S=”Sami”
print (S[-3:])
S[P : P + L]
Ch.lower()
CH =”A”
Ch.upper()

2. //RETURNS CHAR
TO_UPPER(S : STRING)
//RETURNS STRING
TO_LOWER(S : STRING)
RETURNS STRING
S1 & S2
Ch=”a”
S.upper()
S=”sami”
S.lower()
s = S1 + S2
