Interesting facts about strings in Python

In this article, we will learn about some Interesting facts about strings in Python 3.x. Or earlier.

• Immutability
• Auto-detection of escape sequences
• Direct slicing
• Indexed access

Immutability

This means that there is no permission of modification on <string>type and we only have read only access to the strings.

Example

inp = 'Tutorials point'
# output
print(inp)
# assigning a new value to a particular index in a
string
inp[0] = 't'
print(inp) # raises an error

Output

TypeError: 'str' object does not support item assignment

Auto-detection of escape sequences

The strings containing backslash are automatically detected as an escape sequence.

Example

inp = 'Tutorials point'
# output
print(inp+”\n”+”101”)

Output

Tutorials point
101

Direct slicing

We all are aware of substring method in c or c+ +, Slicing does the same operation in python. it takes two compulsory and 1 optional argument. Compulsory arguments are start index (included) and end index(not included) Optional argument is the step or say increment or decement value. By default it is 1.

Example

inp = 'Tutorials point'
# output
print(inp[0:5])

Output

Tutor

Indexed access

As all elements are stored in a contiguous format, therefore we can access elements directly by the help of index.

Example

inp = 'Tutorials point'
# output
print(inp[0]+inp[1])

Output

Tu
