• Python is not compiled (run directly)
• Python is statically typed (the types of the variables cannot change)
• Python is not strongly typed(do not declare types)
• Python does not use curly braces (use tabs and indentations)
• Boolean values are now True and False
• Logic operator are now and or

Strings

• Use single quotes′ double quotes ”

• """triple quotes to comment blocks of code

Access length

• len(s)

Access charAt(index)

• s[index]
• s[-1] -- counts from the end, so last char of the string

Access substring

• s[1:4] -- from 1 to 3, excluding the end
• s[1:4:2] -- from 1 to 3, but stride 2, i.e. skipping every other character
• s[2:] -- from 2 to end
• s[2:10000] -- from 2 to end
• s[:2] -- from start to 1, excluding the end
• s[:] / s[::] -- copy the entire string
• s[::-1] -- copy and reverse the string

Splitting a string

• s.split(' ') -- split by space (only one space)

Remove spaces

• s.strip() -- removes all spaces (front and back) from a string

Compare strings

• s == 'abc' -- compare values

Converting to string

• str(123) -- '123'

For loop

for ... in ... :

        print();

Specifying range

• range(5) -- 0 to 4, excluding the end
• range(0,5) -- -- 0 to 4, excluding the end

Iterate through elements

• forx inarr

Iterate through dictionary

• forkey, vallue indict.items()
