String methods:Python tutorial 18 смотреть онлайн

This video covers many STRING METHODS ( #Boolean methods) #endswith(), #find(), #len(), #upper(), #lower(), #startswith(), #max(), #min(), #count(), #center, #swapcase() etc. Must watch...very useful #methods. Must watch previous videos to make it more clear.Source codes are given below:

STRING METHODS
1.len() function
name="DiVyA ShrIvastAva"
print(len(name))
17

2.lower() method
print(name.lower())
divya shrivastava

3. upper() method
print(name.upper())

5. count() method
print(name.count("i"))
1
print(name.count("a"))

False
a="HELLO"
a.isupper()
