for loop:
A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).
Syntax:
for variable in Sequence
example:
txt = '1234' for num in txt: print(num,end=' ') output: 1 2 3 4
If condition:
The If statement works by checking the expression to see whether a condition is met and returns a value based on the output obtained.
syntax: if condition: if condition is True else: if condition is False
example
x=20 if x>=20: print(x is within 20) else : print(x is above the limit) output: x is within 20
txt = '12a4' for num in txt: if num>='0' and num<='9': print(num,end=' ') else: print('Not Decimal',end=' ') Output: 1 2 Not Decimal 4 above code is the example of combines if and for.
name = input("Your Name please: ")
print(name)
for alphabet in name:
print(alphabet, end='*')
output:
R*A*J*A
The code checks each and every index and prints the output.
name1 = input("Enter the first name: ") name2 = input("Enter the second name: ") name3 = input("Enter the third name: ") name4 = input("Enter the fourth name: ") name = [name1, name2, name3, name4] for letter in name: if letter[0]=='G': print(letter) else: continue for alphabet in name: if alphabet[-1]=='a': print(alphabet) else: continue for alpha in name: for i in alpha: if i==' ': print(alpha) else: continue for character in name: if len(character)>9: print(character) else: continue output: Enter the first name: Guhanraja Enter the second name: Lakshmi Pritha Enter the third name: Guru Prasanna Enter the fourth name: Varatharajan Guhanraja Guru Prasanna Guhanraja Lakshmi Pritha Guru Prasanna Lakshmi Pritha Guru Prasanna Lakshmi Pritha Guru Prasanna Varatharajan
