• immutable
• ''' are used to create docstrings, and multilne strings
• indexing works the same as lists

s1 = 'Hello'
print(s1)
print(type(s1))

# Hello
# <class 'str'>

s = '''
Hey, may name is Afzal
I am 27 years old.
I work as a Project Manager at Coding Ninjas.
'''
print(s)
# Hey, may name is Afzal
# I am 27 years old.
# I work as a Project Manager at Coding Ninjas.

Comparing Strings

• Similar to lists
• Unicode value is compared
• object ID of the strings depends on the platform
• in our system, doesn’t matter if the variable is different, object id stays the same since they have the same contents

str1 = "Ninja"
str2 = "Ninja"
str3 = str1 
  
print("ID of str1 =", hex(id(str1))) 
print("ID of str2 =", hex(id(str2))) 
print("ID of str3 =", hex(id(str3))) 
print(str1 is str1) 
print(str1 is str2) 
print(str1 is str3)

# ID of str1 = 0x7fe6b544fdf0
# ID of str2 = 0x7fe6b544fdf0
# ID of str3 = 0x7fe6b544fdf0
# True
# True
# True

Conversion

• chr() returns a character for ASCII value
• ord() returns the ASCII value for character
