How to use string functions

from m5stack import *
from m5ui import *
from uiflow import *
import binascii

string = None
date = None

string = 'hello world'
print(string.upper())
print('hello')
print(string[0])
print(string.count('o'))
print(not len(string))
print(len(string))
print(string.replace('e', 'w'))
print('   m5stack   '.strip())
print('hello world'.strip('h'))
print(str(2500))
print((str('Hi! ') + str(string)))
date = binascii.hexlify('hello').decode()
print(date.encode())
print((binascii.unhexlify(date)).decode())
print("%.0f"%float(date))
 

API

string = 'helloworld'

Create text content

print(string.upper())

Concatenate text

print(string.upper())

Convert text content to uppercase or lowercase

print(string[0])

Extract a specified portion of text

print(string.count('o'))

Return the number of occurrences of a specified character in the text

print(not len(string)) 

Check if the text is empty

print(len(string))

Return the length of the text

print(str(2500)) 

Convert other data types to strings

print((binascii.unhexlify(date)).decode())

Decode a string to a specified format

print(date.encode())

Convert a string back to a bytes object

date = binascii.hexlify('hello').decode()

Encode a string to bytes

print((binascii.unhexlify(date)).decode())

Convert a string to a String

print("%.0f"%float(date)) 

Perform string formatting to convert a float to a string without a decimal portion

print('')

Print text

print(string.replace('e', 'w')) 

Replace text content

print('   m5stack   '.strip())

Remove leading and trailing whitespace from a string

print('hello world'.strip('h')) 

Specify characters to remove from the beginning and end of a string

print('hello')

Keep the string unescaped, containing all original characters
