Slicing

str = 'some text' 

print(str[0:4])

The first character position is 0 and the length is 4

_var = "Welcome" 
print(_var[3:5])    # 'co'

_var = "Welcome" 
print(_var[3:])      # 'come'

_var = "Welcome" 
print(_var[3])      # 'c'

_var = "Welcome" 
print(_var[0])      # 'w'

_var = "   Welcome   " 
print(_var.strip())      # 'Welcome'

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
