Strings

Can be enclosed in single or double quotes

a ='some text' 
b = "some text" 
print(type(a))      '<class 'str'> 

Multi-Line

We can use three single quotes

myText = '''Some  
Multi Line 
Text'''  
print(myText) 

String Concatenation

Use the plus operator

str1 = "some" 
str2 = "text" 
result = str1 + str2 

print(result[3])       ' positive indices from the left / start  
print(result[-3])       ' negative indices from the right / end  

str3 = ''                  ' empty string 

Slicing

str = 'some text' 

print(str[0:4]) 

The first character position is 0 and the length is 4

str = 'some text' 
print(len(str)) 

SubString Exists

str = "better solutions" 
print(str.split(' ') 

print('better' in str)  

Strings slicing

person_name = "Grace Hopper" 
print(person_name[0])       #= "G" first character 
print(person_name[1])       #= "r" second character 
print(person_name[2])       #= "a" third character 

Strings negative indices

word = "hamster" 
print(word[-1])         #= r 
print(word[1:-1])       #= amste 
print(word[-3:])        #= ter 
print(word[:3])         #= ham 

line continuation - triple quoted strings

my_variable = """This is a long multi-line 
text block. Notice how it can spill onto 
multiple lines. It has been assigned to a new 
variable called my_variable. You can use 'single'  
and "double" quotes inside.""" 
print(my_variable)
