## Ques.Write a program using for loop that loops over a sequence

For loops iterate over a given sequence.In sequence either (dictionary, tuple, set, list and string )

for loop syntax (for variable in sequence or range)

for loop concept Examples

#For loop in list

color_list=['red','green','white','purple','pink','marron']

for i in color_list:

print(i)

#For loop in string

fr_string="Goeduhub technologies"

for i in fr_string:

print(i)

#For loop in dictionary

fr_dict={1:'q',2:'w',3:'e',4:"r"}

for i in fr_dict:

print(i)

#Sum of all the list elements

Num=[1,2,3,4,5,6,7,8,9,10]

Sum=0

for i in Num:

Sum=Sum+i

print(Sum)

Output

red green white purple pink marron

For loop with range()  Function

range() syntax

range(a) - Generates a sequence started from 0 to a , where a is excluded

range(a,b)- Generates a sequence started from a ,end at b , where b is excluded

range(a,b,c)- Generates a sequence started from a, end at (b-1) and c is difference (steps)

Note:-By default range() function take difference of 1, if difference is not given.

Example

color_list=['red','green','white','purple','pink','marron']

for i in range(len(color_list)):

print(color_list[i])

s=0

for i in range(1,14,3):

print(i)

s=s+i

print("sum is =",s)

Output

red green white purple pink marron
