This post some useful tips of using strings, and some issues while dealing with strings

Hope, you have seen Python string format

Check if a string starts with some sequence of characters

to_search = 'my_name'
my_var = 'my_name_is_gorav'
if my_var.startswith(to_search):
    print('Found')

Get substring delimited by some character or string

Example, you have a string:

my_var = 'Name:GyanByte'

You want to have anything after colon

name = my_var.split(':')[1]

Get first letter capital of string

Example: You have some long string like:

name = 'SERVICE_CLOUD_ACCOUNTS'

And, I want something like:

ServiceCloudAccounts

Then, use this code:

new_name = name.title().replace('_', '')

title() method will give you Service_Cloud_Accounts, then we have to remove any other characters we want

Remove any whitespaces around a string, i.e trim

my_str.strip()

Remove multiple spaces with single space

Your string has multiple spaces in between, and you want to convert them into one only.

import re
s = 'hey,    i have  multiple    spaces'
re.sub("\s+", " ", s);

# Output
'hey, i have multiple spaces'

How to add Curly-braces to string in string format

It works perfectly find with following cases

print('{hi}')

print('{hi} %s' %('hi'))

But, not with

website='GyanByte.com'
print(f'hi { {website} .com}')

You have to use Double Curly-braces

website='GyanByte.com'
{% raw %}
print(f'hi {{ {website} .com}}')
{% endraw %}

Get whole string except first letter, or get anything after first character

s = 'GyanByte'
s[1:]
#Output: yanBlog

Get whole string except last letter

s = 'GyanByte'
s[:-1]
