python session day-t payilagam for loop and if condition

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



<p>name = input("Your Name please: ")<br>
print(name)<br>
for alphabet in name:<br>
    print(alphabet, end='*')</p>

<p>output:<br>
R*A*J*A</p>

<p>The code checks each and every index and prints the output.<br>
</p>

<pre class="brush:php;toolbar:false">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
