Python | Add suffix / prefix to strings in a list

Method: Using the + operator + list comprehension

In this task, we simply add a string to the back or front position using the + operator, and list comprehension is used to iterate over all elements.

# Python3 code to demonstrate how it works
# Add suffix / prefix to lines in the list
# Using the comprehension list + operator & quot; + & quot;

  
# initializing list

test_list = [ `a` , `b` , ` c` , `d` ]

  
# print list

print ( "The original list:" + str (test_list))

 
# initializing append_str

append_str = `gfg`

 
# Add suffix / prefix to lines in the list

pre_res = [append_str + sub for sub in test_list]

suf_res = [sub + append_str for sub in test_list]

 
# Print result

print ( "list after prefix addition:" + str (pre_res))

print ( "list after suffix addition:" + str (suf_res))

Output: 

 The original list: [`a`, `b`,` c`, `d`] list after prefix addition: [` gfga`, `gfgb`,` gfgc`, `gfgd`] list afterix addition: [` agfg`, `bgfg`,` cgfg `,` dgfg`]
