Strings can simply be defined by use of single ( ‘ ), double ( ” ) or triple ( ”’ ) inverted commas. Strings enclosed in triple quotes ( ”’ ) can span over multiple lines. A few things to keep in mind about strings:

• Strings are immutable in Python, so you can not change the content of a string.
• Function len() can be used to get length of a string
• You can access the elements using indexes as you do for lists
• You can use ‘+’ operator to concatenate two strings

String ="String elements can also be accessed using index numbers, just like lists"

print (String[0:7])

#Above print command displays "String " on screen.

TASKS TO DO

# Create a string str1
str1 = “Introduction with strings”

# Now store the length of string str1 in variable str_len
str_len = len(str1)

str_new = “Machine Learning is awesome!”
# Print last eight characters of string str_new (the length of str_new is 28 characters).
print(str_new[20:28])

str2 = “I am doing a course Introduction to Hackathon using ”
str3 = “Python”

# Write a line of code to store concatenated string of str2 and str3 into variable str4
str4 = str2 + str3
